Obtain 800 rules for existing CVEs to proactively defend against threats that matter most. Users are urged to upgrade to the latest 2.53 version to prevent potential compromises.īoost your threat detection capabilities and accelerate threat hunting velocity equipped with Sigma, MITRE ATT&CK, and Detection as Code to always have curated detection algorithms against any adversary TTP or any exploitable vulnerability at hand. For now, KeePass v2.5x is considered to be affected. Moreover, the list of affected KeePass versions is still disputed. ![]() Notably, the vendor states that the password database is not intended to be secure against an attacker who has that level of access to a local PC. The PoC exploit for CVE-2023-24055, a scanner for it, and a list of trigger examples were publicly posted on Alex Hernandez’s GitHub. However, a novel vulnerability recently revealed to affect KeePass might expose millions of users to the risk of compromise.Īs explained in the research by Alex Hernandez and detailed in a dedicated SourceForge thread, the vulnerability in question might allow an attacker with write access to the XML configuration file to obtain the cleartext passwords by adding an export trigger. KeePass is an extremely popular free open source tool claimed to be one of the most powerful and secure managers to date.
