The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday  added  a critical security flaw impacting JetBrains TeamCity On-Premises software to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation. The vulnerability, tracked as CVE-2024-27198 (CVSS score: 9.8), refers to an authentication bypass bug that allows for a  complete compromise  of a susceptible server by a remote unauthenticated attacker. It was addressed by JetBrains earlier this week alongside CVE-2024-27199 (CVSS score: 7.3), another moderate-severity authentication bypass flaw that allows for a "limited amount" of information disclosure and system modification. "The vulnerabilities may enable an unauthenticated attacker with HTTP(S) access to a TeamCity server to bypass authentication checks and gain administrative control of that TeamCity server," the company  noted  at the time. Threat actors have been observed weaponizing the twin flaws to de

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a critical security flaw in Citrix ShareFile storage zones controller to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active in-the-wild exploitation. Tracked as  CVE-2023-24489  (CVSS score: 9.8), the shortcoming has been described as an improper access control bug that, if successfully exploited, could allow an unauthenticated attacker to compromise vulnerable instances remotely. The problem is rooted in ShareFile's handling of cryptographic operations, enabling adversaries to upload arbitrary files, resulting in remote code execution. "This vulnerability affects all currently supported versions of customer-managed ShareFile storage zones controller before version 5.11.24," Citrix  said  in an advisory released in June. Dylan Pindur of Assetnote has been credited with discovering and reporting the issue. It's worth noting that the  first signs of exploitatio

It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday  added  a recently disclosed critical flaw impacting Atlassian's Bitbucket Server and Data Center to the Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. Tracked as  CVE-2022-36804 , the issue relates to a command injection vulnerability that could allow malicious actors to gain arbitrary code execution on susceptible installations by sending a specially crafted HTTP request. Successful exploitation, however, banks on the prerequisite that the attacker already has access to a public repository or possesses read permissions to a private Bitbucket repository. "All versions of Bitbucket Server and Datacenter released after 6.10.17 including 7.0.0 and newer are affected, this means that all instances that are running any versions between 7.0.0 and 8.3.0 inclusive are affected by this vulnerability," Atlassian  noted  in a late August 2022 advisory.
