Recent SSRF Flaw in Ivanti VPN Products Undergoes Mass Exploitation

Recent SSRF Flaw in Ivanti VPN Products Undergoes Mass Exploitation

Feb 06, 2024 Cybersecurity / Vulnerability
A recently disclosed server-side request forgery ( SSRF ) vulnerability impacting Ivanti Connect Secure and Policy Secure products has come under mass exploitation. The Shadowserver Foundation  said  it observed exploitation attempts originating from more than 170 unique IP addresses that aim to establish a reverse shell, among others. The attacks exploit  CVE-2024-21893  (CVSS score: 8.2), an SSRF flaw in the SAML component of Ivanti Connect Secure, Policy Secure, and Neurons for ZTA that allows an attacker to access otherwise restricted resources without authentication. Ivanti had previously divulged that the vulnerability had been exploited in targeted attacks aimed at a "limited number of customers," but cautioned the status quo could change post public disclosure. That's exactly what appears to have happened, especially following the  release  of a proof-of-concept (PoC) exploit by cybersecurity firm Rapid7 last week. The PoC involves fashioning an exploit cha
New Threat Actor 'AeroBlade' Emerges in Espionage Attack on U.S. Aerospace

New Threat Actor 'AeroBlade' Emerges in Espionage Attack on U.S. Aerospace

Dec 05, 2023 Cyber Espionage / Threat Analysis
A previously undocumented threat actor has been linked to a cyber attack targeting an aerospace organization in the U.S. as part of what's suspected to be a cyber espionage mission. The BlackBerry Threat Research and Intelligence team is tracking the activity cluster as  AeroBlade . Its origin is currently unknown and it's not clear if the attack was successful. "The actor used spear-phishing as a delivery mechanism: A weaponized document, sent as an email attachment, contains an embedded remote template injection technique and a malicious VBA macro code, to deliver the next stage to the final payload execution," the company  said  in an analysis published last week. The network infrastructure used for the attack is said to have gone live around September 2022, with the offensive phase of the intrusion occurring nearly a year later in July 2023, but not before the adversary took steps to improvise its toolset to make it more stealthy in the intervening time perio
SaaS Compliance through the NIST Cybersecurity Framework

SaaS Compliance through the NIST Cybersecurity Framework

Feb 20, 2024Cybersecurity Framework / SaaS Security
The US National Institute of Standards and Technology (NIST) cybersecurity framework is one of the world's most important guidelines for securing networks. It can be applied to any number of applications, including SaaS.  One of the challenges facing those tasked with securing SaaS applications is the different settings found in each application. It makes it difficult to develop a configuration policy that will apply to an HR app that manages employees, a marketing app that manages content, and an R&D app that manages software versions, all while aligning with NIST compliance standards.  However, there are several settings that can be applied to nearly every app in the SaaS stack. In this article, we'll explore some universal configurations, explain why they are important, and guide you in setting them in a way that improves your SaaS apps' security posture.  Start with Admins Role-based access control (RBAC) is a key to NIST adherence and should be applied to every SaaS a
New BLUFFS Bluetooth Attack Expose Devices to Adversary-in-the-Middle Attacks

New BLUFFS Bluetooth Attack Expose Devices to Adversary-in-the-Middle Attacks

Dec 04, 2023 Encryption / Technology
New research has unearthed multiple novel attacks that break Bluetooth Classic's forward secrecy and future secrecy guarantees, resulting in adversary-in-the-middle (AitM) scenarios between two already connected peers. The issues, collectively named  BLUFFS , impact Bluetooth Core Specification 4.2 through 5.4. They are tracked under the identifier  CVE-2023-24023  (CVSS score: 6.8) and were responsibly disclosed in October 2022. The attacks "enable device impersonation and machine-in-the-middle across sessions by only compromising one session key," EURECOM researcher Daniele Antonioli said in a study published late last month. This is made possible by leveraging two new flaws in the Bluetooth standard's session key derivation mechanism that allow the derivation of the same key across sessions. While forward secrecy in key-agreement cryptographic protocols ensures that past communications are not revealed, even if the private keys to a particular exchange are re
