The list of vulnerabilities is as follows - CVE-2024-11639 (CVSS score: 10.0) - An authentication bypass vulnerability in the admin web console of Ivanti CSA before 5.0.3 that allows a remote unauthenticated attacker to gain administrative access CVE-2024-11772 (CVSS score: 9.1) - A command injection vulnerability in the admin web console of Ivanti CSA before version 5.0.3 that allows a remote authenticated attacker with admin privileges to achieve remote code execution CVE-2024-11773 (CVSS score: 9.1) - An SQL injection vulnerability in the admin web console of Ivanti CSA before version 5.0.3 that allows a remote authenticated attacker with admin privileges to run arbitrary SQL statements CVE-2024-11633 (CVSS score: 9.1) - An argument injection vulnerability in Ivanti Con...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday added a security flaw impacting Ivanti Endpoint Manager (EPM) that the company patched in May to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation. The vulnerability, tracked as CVE-2024-29824 , carries a CVSS score of 9.6 out of a maximum of 10.0, indicating critical severity. "An unspecified SQL Injection vulnerability in Core server of Ivanti EPM 2022 SU5 and prior allows an unauthenticated attacker within the same network to execute arbitrary code," the software service provider said in an advisory released on May 21, 2024. Horizon3.ai, which released a proof-of-concept (PoC) exploit for the flaw in June, said the issue is rooted in a function called RecordGoodApp() within a DLL named PatchBiz.dll. Specifically, it concerns how the function handles an SQL query statement, thereby allowing an attacker to gain remote code execution via xp_cmdshe...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...

Ivanti has revealed that a newly patched security flaw in its Cloud Service Appliance (CSA) has come under active exploitation in the wild. The high-severity vulnerability in question is CVE-2024-8190 (CVSS score: 7.2), which allows remote code execution under certain circumstances. "An OS command injection vulnerability in Ivanti Cloud Services Appliance versions 4.6 Patch 518 and before allows a remote authenticated attacker to obtain remote code execution," Ivanti noted in an advisory released earlier this week. "The attacker must have admin level privileges to exploit this vulnerability." The flaw impacts Ivanti CSA 4.6, which has currently reached end-of-life status, requiring that customers upgrade to a supported version going forward. That said, it has been addressed in CSA 4.6 Patch 519. "With the end-of-life status this is the last fix that Ivanti will backport for this version," the Utah-based IT software company added. "Customers mus...

The MITRE Corporation has revealed that the cyber attack targeting the not-for-profit company towards late December 2023 by exploiting zero-day flaws in Ivanti Connect Secure (ICS) involved the threat actor creating rogue virtual machines (VMs) within its VMware environment. "The adversary created their own rogue VMs within the VMware environment, leveraging compromised vCenter Server access," MITRE researchers Lex Crumpton and Charles Clancy  said . "They wrote and deployed a JSP web shell (BEEFLUSH) under the vCenter Server's Tomcat server to execute a Python-based tunneling tool, facilitating SSH connections between adversary-created VMs and the ESXi hypervisor infrastructure." The motive behind such a move is to sidestep detection by obscuring their malicious activities from centralized management interfaces like vCenter and maintain persistent access while reducing the risk of being discovered. Details of the attack  emerged  last month when MITRE rev...

Ivanti on Tuesday rolled out fixes to address multiple critical security flaws in Endpoint Manager (EPM) that could be exploited to achieve remote code execution under certain circumstances. Six of the 10 vulnerabilities – from  CVE-2024-29822 through CVE-2024-29827  (CVSS scores: 9.6) – relate to SQL injection flaws that allow an unauthenticated attacker within the same network to execute arbitrary code. The remaining four bugs -- CVE-2024-29828, CVE-2024-29829, CVE-2024-29830, and CVE-2024-29846 (CVSS scores: 8.4) -- also fall under the same category with the only change being that they require the attacker to be authenticated. The shortcomings impact the Core server of Ivanti EPM versions 2022 SU5 and prior. The company has also  addressed  a high-severity security flaw in Avalanche version 6.4.3.602 (CVE-2024-29848, CVSS score: 7.2) that could permit an attacker to achieve remote code execution by uploading a specially crafted file. In addition, patches ha...

The MITRE Corporation has offered more details into the recently disclosed cyber attack, stating that the first evidence of the intrusion now dates back to December 31, 2023. The attack, which  came to light last month , singled out MITRE's Networked Experimentation, Research, and Virtualization Environment (NERVE) through the exploitation of two Ivanti Connect Secure zero-day vulnerabilities tracked as CVE-2023–46805 and CVE-2024–21887, respectively. "The adversary maneuvered within the research network via VMware infrastructure using a compromised administrator account, then employed a combination of backdoors and web shells to maintain persistence and harvest credentials," MITRE  said . While the organization had previously disclosed that the attackers performed reconnaissance of its networks starting in January 2024, the latest technical deep dive puts the earliest signs of compromise in late December 2023, with the adversary dropping a Perl-based web shell ...

Multiple China-nexus threat actors have been linked to the zero-day exploitation of three security flaws impacting Ivanti appliances (CVE-2023-46805, CVE-2024-21887, and CVE-2024-21893). The clusters are being tracked by Mandiant under the uncategorized monikers  UNC5221 , UNC5266, UNC5291,  UNC5325 , UNC5330, and UNC5337. Also previously linked to the exploitation spree is a Chinese hacking crew called UNC3886 , whose tradecraft is notable for weaponizing zero-day bugs in Fortinet and VMware to breach target networks. The Google Cloud subsidiary said it has also observed financially motivated actors exploiting CVE-2023-46805 and CVE-2024-21887, likely in an attempt to conduct cryptocurrency mining operations. "UNC5266 overlaps in part with UNC3569, a China-nexus espionage actor that has been observed exploiting vulnerabilities in Aspera Faspex, Microsoft Exchange, and Oracle Web Applications Desktop Integrator, among others, to gain initial access to target environments,...

Ivanti has released security updates to address four security flaws impacting Connect Secure and Policy Secure Gateways that could result in code execution and denial-of-service (DoS). The list of flaws is as follows - CVE-2024-21894  (CVSS score: 8.2) - A heap overflow vulnerability in the IPSec component of Ivanti Connect Secure (9.x, 22.x) and Ivanti Policy Secure allows an unauthenticated malicious user to send specially crafted requests in order to crash the service thereby causing a DoS attack. In certain conditions, this may lead to execution of arbitrary code.

It credited Vincent Hutsebaut, Pierre Vivegnis, Jerome Nokin, Roberto Suggi Liverani and Antonin B. of NATO Cyber Security Centre for "their collaboration on this issue." Ivanti emphasized that it's not aware of any customers affected by CVE-2023-41724, and  added  that ...

The Five Eyes (FVEY) intelligence alliance has issued a new cybersecurity advisory warning of cyber threat actors exploiting known security flaws in Ivanti Connect Secure and Ivanti Policy Secure gateways, noting that the Integrity Checker Tool (ICT) can be deceived to provide a false sense of security. "Ivanti ICT is not sufficient to detect compromise and that a cyber threat actor may be able to gain root-level persistence despite issuing factory resets," the agencies  said . To date, Ivanti has disclosed five security vulnerabilities impacting its products since January 10, 2024, out of which four have come under active exploitation by multiple threat actors to deploy malware - CVE-2023-46805  (CVSS score: 8.2) - Authentication bypass vulnerability in web component CVE-2024-21887  (CVSS score: 9.1) - Command injection vulnerability in web component CVE-2024-21888  (CVSS score: 8.8) - Privilege escalation vulnerability in web component CVE-2024-21893  ...

A reverse engineering of the firmware running on Ivanti Pulse Secure appliances has revealed numerous weaknesses, once again underscoring the challenge of securing software supply chains. Eclypsiusm, which acquired firmware version 9.1.18.2-24467.1 as part of the process, said the base operating system used by the Utah-based software company for the device is CentOS 6.4. "Pulse Secure runs an 11-year-old version of Linux which hasn't been supported since November 2020," the firmware security company  said  in a report shared with The Hacker News. The development comes as threat actors are capitalizing on a number of security flaws discovered in Ivanti Connect Secure, Policy Secure, and ZTA gateways to  deliver  a  wide range of malware , including web shells, stealers, and backdoors. The vulnerabilities that have come under active exploitation in recent months comprise CVE-2023-46805, CVE-2024-21887, and CVE-2024-21893. Last week, Ivanti also  disclose...

Threat actors are leveraging a recently disclosed security flaw impacting Ivanti Connect Secure, Policy Secure, and ZTA gateways to deploy a backdoor codenamed  DSLog  on susceptible devices. That's according to  findings  from Orange Cyberdefense, which said it observed the exploitation of CVE-2024-21893 within hours of the public release of the proof-the-concept (PoC) code. CVE-2024-21893, which was  disclosed  by Ivanti late last month alongside CVE-2024-21888, refers to a server-side request forgery (SSRF) vulnerability in the SAML module that, if successfully exploited, could permit access to otherwise restricted resources sans any authentication. The Utah-based company has since acknowledged that the flaw has limited targeted attacks, although the exact scale of the compromises is unclear. Then, last week, the Shadowserver Foundation  revealed  a surge in exploitation attempts targeting the vulnerability originating from over 170 uniqu...

Ivanti has alerted customers of yet another high-severity security flaw in its Connect Secure, Policy Secure, and ZTA gateway devices that could allow attackers to bypass authentication. The issue, tracked as  CVE-2024-22024 , is rated 8.3 out of 10 on the CVSS scoring system. "An XML external entity or XXE vulnerability in the SAML component of Ivanti Connect Secure (9.x, 22.x), Ivanti Policy Secure (9.x, 22.x) and ZTA gateways which allows an attacker to access certain restricted resources without authentication," the company  said  in an advisory. The company said it discovered the flaw during an internal review as part of its ongoing investigation into multiple security weaknesses in the products that have come to light since the start of the year, including  CVE-2023-46805, CVE-2024-21887 ,  CVE-2024-21888, and CVE-2024-21893 . CVE-2024-22024 affects the following versions of the products - Ivanti Connect Secure (versions 9.1R14.4, 9.1R17.2, 9.1R18....

Google-owned Mandiant said it identified new malware employed by a China-nexus espionage threat actor known as UNC5221 and other threat groups during post-exploitation activity targeting Ivanti Connect Secure VPN and Policy Secure devices. This includes custom web shells such as BUSHWALK, CHAINLINE, FRAMESTING, and a variant of  LIGHTWIRE . "CHAINLINE is a Python web shell backdoor that is embedded in a Ivanti Connect Secure Python package that enables arbitrary command execution," the company  said , attributing it to UNC5221, adding it also detected multiple new versions of  WARPWIRE , a JavaScript-based credential stealer. The infection chains entail a successful exploitation of  CVE-2023-46805 and CVE-2024-21887 , which allow an unauthenticated threat actor to execute arbitrary commands on the Ivanti appliance with elevated privileges. The flaws have been abused as zero-days since early December 2023. Germany's Federal Office for Information Security (BSI)...

Ivanti is alerting of two new high-severity flaws in its Connect Secure and Policy Secure products, one of which is said to have come under targeted exploitation in the wild. The list of vulnerabilities is as follows - CVE-2024-21888  (CVSS score: 8.8) - A privilege escalation vulnerability in the web component of Ivanti Connect Secure (9.x, 22.x) and Ivanti Policy Secure (9.x, 22.x) allows a user to elevate privileges to that of an administrator CVE-2024-21893  (CVSS score: 8.2) - A server-side request forgery vulnerability in the SAML component of Ivanti Connect Secure (9.x, 22.x), Ivanti Policy Secure (9.x, 22.x) and Ivanti Neurons for ZTA allows an attacker to access certain restricted resources without authentication The Utah-based software company  said  it found no evidence of customers being impacted by CVE-2024-21888 so far, but acknowledged "the exploitation of CVE-2024-21893 appears to be targeted" and that it's "aware of a limited number of cust...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday issued an  emergency directive  urging Federal Civilian Executive Branch (FCEB) agencies to implement mitigations against two actively exploited zero-day flaws in Ivanti Connect Secure (ICS) and Ivanti Policy Secure (IPS) products. The development arrives as the  vulnerabilities  – an authentication bypass (CVE-2023-46805) and a code injection bug (CVE-2024-21887) – have come under widespread exploitation by multiple threat actors. The flaws allow a malicious actor to craft malicious requests and execute arbitrary commands on the system. The U.S. company  acknowledged  in an advisory that it has witnessed a "sharp increase in threat actor activity" starting on January 11, 2024, after the shortcomings were publicly disclosed. "Successful exploitation of the vulnerabilities in these affected products allows a malicious threat actor to move laterally, perform data exfiltration, and...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday  added  a now-patched critical flaw impacting Ivanti Endpoint Manager Mobile (EPMM) and MobileIron Core to its Known Exploited Vulnerabilities ( KEV ) catalog, stating it's being actively exploited in the wild. The vulnerability in question is  CVE-2023-35082  (CVSS score: 9.8), an authentication bypass that's a patch bypass for another flaw in the same solution tracked as CVE-2023-35078 (CVSS score: 10.0), which was actively exploited in attacks targeted Norwegian government entities as a zero-day in April 2023. "If exploited, this vulnerability enables an unauthorized, remote (internet-facing) actor to potentially access users' personally identifiable information and make limited changes to the server," Ivanti  noted  in August 2023. All versions of Ivanti Endpoint Manager Mobile (EPMM) 11.10, 11.9 and 11.8, and MobileIron Core 11.7 and below are impacted by the vulnerabilit...

A pair of zero-day flaws identified in Ivanti Connect Secure (ICS) and Policy Secure have been chained by suspected China-linked nation-state actors to breach less than 10 customers. Cybersecurity firm Volexity, which  identified  the activity on the network of one of its customers in the second week of December 2023, attributed it to a hacking group it tracks under the name  UTA0178 . There is evidence to suggest that the VPN appliance may have been compromised as early as December 3, 2023. The two vulnerabilities that have been exploited in the wild to achieve unauthenticated command execution on the ICS device are as follows - CVE-2023-46805  (CVSS score: 8.2) - An authentication bypass vulnerability in the web component of Ivanti Connect Secure (9.x, 22.x) and Ivanti Policy Secure allows a remote attacker to access restricted resources by bypassing control checks.
