The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday issued a bulletin warning of a zero-day flaw affecting Zoho ManageEngine ADSelfService Plus deployments that is currently being actively exploited in the wild. The flaw, tracked as  CVE-2021-40539 , concerns a REST API authentication bypass that could lead to arbitrary remote code execution (RCE). ADSelfService Plus builds up to 6113 are impacted. ManageEngine ADSelfService Plus is an integrated self-service password management and a single sign-on solution for Active Directory and cloud apps, enabling admins to enforce two-factor authentication for application logins and users to reset their passwords. "CVE-2021-40539 has been detected in exploits in the wild. A remote attacker could exploit this vulnerability to take control of an affected system," CISA  said , urging companies to apply the latest security update to their ManageEngine servers and "ensure ADSelfService Plus is not directl...

The work-from-anywhere economy has opened up the possibility for your human resources team to source the best talent from anywhere. To scale their operations, organizations are leveraging the cloud to accelerate essential HR functions such as recruiting, onboarding, evaluating, and more. SAP is leading this HR transformation with its human capital management (HCM) solution, SAP SuccessFactors. Delivering HR solutions from the cloud enables employees and administrators to not only automate typical tasks, such as providing a report on employee attrition, but also allows them to complete these tasks from anywhere and on any device. SuccessFactors makes it easy for employees to access what they need. But the wide range of sensitive employee data within SuccessFactors creates additional security and compliance challenges. Whether it's personal and financial information used for payroll or health information for benefits, you need the right cybersecurity to ensure that sensitive data,...

A critical security vulnerability has been disclosed in  HAProxy , a widely used open-source load balancer and proxy server, that could be abused by an adversary to possibly smuggle HTTP requests, resulting in unauthorized access to sensitive data and execution of arbitrary commands, effectively opening the door to an array of attacks. Tracked as  CVE-2021-40346 , the Integer Overflow vulnerability has a severity rating of 8.6 on the CVSS scoring system and has been rectified in HAProxy versions 2.0.25, 2.2.17, 2.3.14 and 2.4.4. HTTP Request Smuggling, as the name implies, is a web application attack that tampers the manner a website processes sequences of HTTP requests received from more than one user. Also called HTTP desynchronization, the technique takes advantage of parsing inconsistencies in how front-end servers and back-end servers process requests from the senders. Front-end servers are typically load balancers or reverse proxies that are used by websites to mana...

Cybersecurity researchers on Tuesday released new findings that reveal a year-long mobile espionage campaign against the Kurdish ethnic group to deploy two Android backdoors that masquerade as legitimate apps. Active since at least March 2020, the attacks leveraged as many as six dedicated Facebook profiles that claimed to offer tech and pro-Kurd content — two aimed at Android users while the other four appeared to provide news for the Kurdish supporters — only to share links to spying apps on public Facebook groups. All the six profiles have since been taken down. "It targeted the Kurdish ethnic group through at least 28 malicious Facebook posts that would lead potential victims to download Android 888 RAT or SpyNote," ESET researcher Lukas Stefanko  said . "Most of the malicious Facebook posts led to downloads of the commercial, multi-platform 888 RAT, which has been available on the black market since 2018." The Slovakian cybersecurity firm attributed the at...

Most cyber security today involves much more planning, and much less reacting than in the past. Security teams spend most of their time preparing their organizations' defenses and doing operational work. Even so, teams often must quickly spring into action to respond to an attack. Security teams with copious resources can quickly shift between these two modes. They have enough resources to allocate to respond properly. Lean IT security teams, however, are more hard-pressed to react effectively. A new guide by XDR provider Cynet ( download here ), however, argues that lean teams can still respond effectively. It just takes some work.  For teams that are resource-constrained, success starts with having a clear plan and putting the tools and infrastructure in place for the organization to follow properly. The guide breaks down the tools, factors, and knowledge that go into optimizing an organization's time to respond.  Building a successful incident response plan Today's ...

Microsoft on Tuesday warned of an actively exploited zero-day flaw impacting Internet Explorer that's being used to hijack vulnerable Windows systems by leveraging weaponized Office documents. Tracked as CVE-2021-40444 (CVSS score: 8.8), the remote code execution flaw is rooted in MSHTML (aka Trident), a proprietary browser engine for the now-discontinued Internet Explorer and which is used in Office to render web content inside Word, Excel, and PowerPoint documents. "Microsoft is investigating reports of a remote code execution vulnerability in MSHTML that affects Microsoft Windows. Microsoft is aware of targeted attacks that attempt to exploit this vulnerability by using specially-crafted Microsoft Office documents," the company  said . "An attacker could craft a malicious ActiveX control to be used by a Microsoft Office document that hosts the browser rendering engine. The attacker would then have to convince the user to open the malicious document. Users who...

The maintainers of Jenkins—a popular open-source automation server software—have disclosed a security breach after unidentified threat actors gained access to one of their servers by exploiting a recently disclosed vulnerability in Atlassian Confluence service to install a cryptocurrency miner. The "successful attack," which is believed to have occurred last week, was mounted against its Confluence service that had been deprecated since October 2019, leading the team to take the server offline, rotate privileged credentials, and reset passwords for developer accounts. "At this time we have no reason to believe that any Jenkins releases, plugins, or source code have been affected," the company  said  in a statement published over the weekend. The disclosure comes as the U.S. Cyber Command  warned  of ongoing mass exploitation attempts in the wild targeting a now-patched critical security vulnerability affecting Atlassian Confluence deployments. Tracked as CVE-2...
