CVE-2025-12744
Published: 03 December 2025
Summary
CVE-2025-12744 is a high-severity OS Command Injection (CWE-78) vulnerability. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 25.5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
SI-10 requires input validation at entry points, directly preventing command injection from untrusted user-supplied mount information inserted into shell commands.
SI-2 mandates timely flaw remediation, addressing the specific command injection vulnerability in the ABRT daemon by applying patches.
AC-6 enforces least privilege on the root-running ABRT process, limiting the impact of injected commands even if validation fails.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
The vulnerability is a command injection flaw in a root-running daemon (ABRT), directly enabling exploitation for local privilege escalation from unprivileged user to root.
NVD Description
A flaw was found in the ABRT daemon’s handling of user-supplied mount information.ABRT copies up to 12 characters from an untrusted input and places them directly into a shell command (docker inspect %s) without proper validation. An unprivileged local user…

can craft a payload that injects shell metacharacters, causing the root-running ABRT process to execute attacker-controlled commands and ultimately gain full root privileges.
Deeper analysisAI
CVE-2025-12744 is a command injection vulnerability (CWE-78) in the ABRT daemon's handling of user-supplied mount information. The daemon copies up to 12 characters from untrusted input and inserts them directly into a shell command ("docker inspect %s") without proper validation. This flaw affects the ABRT component, primarily in Red Hat environments, and carries a CVSS v3.1 base score of 8.8 (AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H). It was published on 2025-12-03.
An unprivileged local user can exploit the vulnerability by crafting a payload containing shell metacharacters. When processed, this injects arbitrary commands into the root-running ABRT process, enabling execution of attacker-controlled code and full root privilege escalation.
