CVE-2026-105324
CriticalCVSS 9.2Summary
An HTTP header injection vulnerability in start-page-loader.cgi of ADM allows an unauthenticated remote attacker to read arbitrary files on the host system. By sending a crafted HTTP request with injected headers via the state parameter, the attacker can leverage the underlying web server's X-Sendfile mechanism to retrieve sensitive files without authentication.
Risk Assessment
An unauthenticated attacker can access sensitive system files, potentially leading to data leakage and further system compromise.
Recommendation
Update ADM to a non-vulnerable version and restrict access to network services.
Other vulnerabilities in ADM
See all- CVE-2026-67248High
A stack-based buffer overflow vulnerability was found in the File Explorer on ADM. User-controlled input is not properly validated before being decoded and copied into a fixed-size stack buffer, potentially causing denial of service of the CGI process.
- CVE-2026-67247Medium
A path traversal vulnerability was found in the IHM Log handling of ADM. User-controlled disk serial input is not sufficiently validated before being used to construct the path of an IHM log database file.
- CVE-2026-67246Medium
A path traversal vulnerability in the Wallpaper component of ADM. User-controlled wallpaper path input is not sufficiently validated, allowing access to files outside the intended wallpaper directory.
