CVE-2025-12744 is an OS command injection vulnerability discovered in the ABRT (Automatic Bug Reporting Tool) daemon, which is used primarily in Fedora and related Linux distributions for automated crash reporting. The vulnerability arises from improper neutralization of special elements in user-supplied mount information. Specifically, ABRT copies up to 12 characters from untrusted input and inserts them directly into a shell command: 'docker inspect %s', without adequate validation or sanitization. This allows an unprivileged local user to craft a malicious payload containing shell metacharacters that break out of the intended command context and execute arbitrary commands with root privileges, since ABRT runs as root. The vulnerability requires local access and low privileges but no user interaction, making it easier to exploit in environments where users have shell access. The CVSS 3.1 score of 8.8 reflects high impact on confidentiality, integrity, and availability, with low attack complexity and privileges required. Although no public exploits are known yet, the flaw poses a critical risk for privilege escalation and full system compromise. The vulnerability affects all versions of ABRT prior to the patch, and the lack of patch links suggests fixes may be forthcoming or in progress. The flaw is particularly dangerous in multi-user systems or environments where untrusted users have shell access, as it can lead to root takeover and subsequent lateral movement or data exfiltration.

For European organizations, the impact of CVE-2025-12744 can be severe, especially in sectors relying on Fedora or similar Linux distributions for critical infrastructure, servers, or development environments. Successful exploitation allows local attackers to escalate privileges to root, potentially leading to full system compromise, unauthorized data access, disruption of services, and deployment of persistent malware. Confidentiality is at high risk as attackers can access sensitive data, integrity is compromised through unauthorized command execution, and availability can be affected by destructive payloads or system instability. Organizations with multi-user environments, shared hosting, or developer workstations are particularly vulnerable. The vulnerability could also facilitate lateral movement within networks, increasing the attack surface. Given the high CVSS score and root-level impact, failure to address this vulnerability could result in significant operational and reputational damage, regulatory penalties under GDPR if personal data is exposed, and increased risk of targeted attacks leveraging this privilege escalation vector.

To mitigate CVE-2025-12744, European organizations should: 1) Immediately monitor vendor advisories and apply official patches or updates to the ABRT daemon as soon as they become available. 2) Restrict local user access to trusted personnel only, minimizing the number of unprivileged users with shell access on affected systems. 3) Implement strict access controls and user privilege management to limit the ability of unprivileged users to interact with ABRT or execute commands. 4) Temporarily disable or restrict the ABRT service if patching is not immediately possible, especially on multi-user systems. 5) Employ application whitelisting and command execution monitoring to detect anomalous use of docker or shell commands initiated by ABRT. 6) Conduct regular audits of system logs for suspicious activity related to ABRT or docker commands. 7) Educate system administrators and users about the risks of local privilege escalation vulnerabilities and the importance of timely patching. 8) Consider container security best practices, as the vulnerability involves docker commands, to limit container escape or misuse. These steps go beyond generic advice by focusing on controlling local access, monitoring specific command usage, and prioritizing patch management in affected environments.
