HighCVSS 8.1Exploitation Probability (EPSS)
Low risk13th percentile - higher than 13% of all known CVEs
Summary
A format string vulnerability in the Internal Backup function of ADM. User-controlled task input is processed unsafely, allowing memory information disclosure or denial of service.
Risk Assessment
An authenticated attacker can access sensitive memory data or cause the CGI process to become unavailable, affecting system operations.
Recommendation
Update ADM to a version later than 4.3.3.RUN1 or 5.1.3.RI81, depending on the branch used.
Other vulnerabilities in ADM
See all- CVE-2026-67248High
