A format string vulnerability was found in the Rsync Backup on the ADM. The vulnerability occurs because user-controlled rsync backup configuration or log data may be processed through an unsafe format string operation. An authenticated attacker can exploit this issue to disclose memory information or cause denial of service of the affected backup component. Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.RUN1 as well as from ADM 5.0.0 through ADM 5.1.3.RI81.
AI Analysis
Technical Summary
CVE-2026-18188 is a format string vulnerability in the Rsync Backup feature of ADM devices. The issue occurs because user-controlled input in rsync backup configuration or logs is processed unsafely via format string operations, leading to potential memory disclosure or denial of service. The vulnerability requires authentication to exploit. Affected versions are ADM 4.1.0 through 4.3.3.RUN1 and ADM 5.0.0 through 5.1.3.RI81. There is no indication of known exploits in the wild or available patches at this time.
Potential Impact
An authenticated attacker can leverage this vulnerability to disclose sensitive memory information or cause a denial of service on the affected backup component. This could impact the availability and confidentiality of the backup service on ADM devices within the specified version ranges.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the Rsync Backup configuration and logs to trusted authenticated users only to reduce exploitation risk.
