This vulnerability allows an attacker, who has write access to the XML configuration file, to obtain the cleartext passwords by adding an export trigger. It affects KeePass through version 2.53, which poses a medium risk to organizations. The CVSS score for this vulnerability is 5.5, indicating that it is of medium severity. Even though the impact is high in terms of confidentiality, the attack complexity is low, and no privileges are required for exploitation. As such, organizations should prioritize patching immediately.
Risk to organizations includes unauthorized access to sensitive passwords, potentially leading to further compromises or data breaches. This vulnerability has been classified under CWE-312, indicating a risk associated with the exposure of sensitive information. Although there is no confirmed public exploit available for this vulnerability, the presence of multiple proof of concept (PoC) repositories on GitHub suggests that attackers may develop methods to exploit this flaw.
Organizations should address this vulnerability in their priority patch cycle to mitigate the associated risks effectively. Although the vendor has stated that the password database is not intended to be secure against attackers with local access, it remains critical for users to implement best practices in securing access to their systems.
The urgency to remediate this vulnerability is underscored by its potential impact. The CVSS score indicates that while the exploitation may require some level of user interaction, the overall risk remains significant. Therefore, organizations must take proactive measures to ensure that their KeePass installations are updated and configured securely.
Vulnerability Details
KeePass through 2.53 (in a default installation) allows an attacker, who has write access to the XML configuration file, to obtain the cleartext passwords by adding an export trigger. The vendor's position is that the password database is not intended to be secure against an attacker who has that level of access to the local PC.
The CVSS score is 5.5, representing medium severity. The attack vector is categorized as local, with low complexity. No privileges are required, but user interaction is necessary for exploitation. The confidentiality impact is high, while the integrity and availability impacts are none.
Technical Analysis
The root cause of this vulnerability lies in the insecure handling of the XML configuration file. Attackers with local access can modify this file to introduce an export trigger, allowing them to extract sensitive information. With low attack complexity and no required privileges, the barrier to exploitation is minimal, making this a significant risk.
The attack vector requires local access to the system, which means that physical or remote access via another compromised account could enable an attacker to exploit this vulnerability. Although user interaction is required to trigger the exploit, the consequences can be severe, given the high confidentiality impact.
This vulnerability is particularly concerning for users who store sensitive information in KeePass. Organizations must ensure that access to the configuration file is tightly controlled and that users are educated about the risks of unauthorized access.
Risk & Impact Analysis
Real-world deployment risk stems from the ease with which an attacker can gain local access to the KeePass database and configuration files. The blast radius for this vulnerability includes any environment where KeePass is used, particularly in organizations handling sensitive data.
This vulnerability highlights the importance of securing local systems, as attackers may exploit weaknesses in physical security or user behavior to gain access. Organizations must assess their security posture and implement necessary controls to mitigate risks associated with this vulnerability.
The urgency of addressing this vulnerability is reflected in its CVSS score and the potential for exploitation. Organizations should prioritize remediation efforts to minimize the risk of unauthorized access to sensitive information.

Affected Versions
All versions of KeePass prior to version 2.53 are affected. Organizations must ensure they upgrade to the latest version to mitigate the risks associated with this vulnerability.
Mitigation & Remediation
Organizations should prioritize upgrading to the latest version of KeePass to remediate this vulnerability. If an upgrade is not immediately possible, consider implementing access controls to restrict write access to the XML configuration file. Additionally, monitoring for unauthorized modifications to this file can help in early detection of potential exploits.
For further guidance, organizations can refer to resources on penetration testing to identify security weaknesses in their environment.
Detection Guidance
Security teams should monitor logs for any unauthorized access attempts to the XML configuration file and look for behavioral anomalies in KeePass usage. Additionally, setting up network signatures to identify unusual export commands can aid in detection.
