Mitigating Controls (NIST 800-53 r5)AI
Directly prevents command injection by validating and sanitizing the Name argument in the revertBackup function before command execution.
Establishes processes to identify, assess, and remediate flaws like this unpatched command injection in dst-admin up to 1.5.0.
Reduces impact of exploited command injection by enforcing least privilege on the low-privilege account required for remote access.
Security SummaryAI
CVE-2026-2956 is a command injection vulnerability (CWE-74, CWE-77) affecting qinming99 dst-admin versions up to 1.5.0. The issue lies in the revertBackup function of the /home/restore file, where manipulation of the Name argument allows attackers to inject and execute arbitrary commands.
The vulnerability enables remote exploitation (AV:N) with low attack complexity (AC:L) and requires low privileges (PR:L) but no user interaction (UI:N), with unchanged scope (S:U). Successful exploitation results in low impacts to confidentiality, integrity, and availability (C:L/I:L/A:L), yielding a CVSS 3.1 base score of 6.3.
Advisories from VULDB note that the vendor was contacted early regarding disclosure but provided no response, and no patches or official mitigations are available. An exploit has been publicly released, heightening the potential for real-world attacks.
