DescriptionNVD

A buffer over-read in Util_urlDecode in util.c in Tildeslash Monit before 5.25.3 allows a remote authenticated attacker to retrieve the contents of adjacent memory via manipulation of GET or POST parameters. The attacker can also cause a denial of service (application outage).

AnalysisAI

A buffer over-read in Util_urlDecode in util.c in Tildeslash Monit before 5.25.3 allows a remote authenticated attacker to retrieve the contents of adjacent memory via manipulation of GET or POST. Rated high severity (CVSS 8.1), this vulnerability is remotely exploitable, low attack complexity. Public exploit code available.

Technical ContextAI

This vulnerability is classified as Out-of-bounds Read (CWE-125), which allows attackers to read data from memory outside the intended buffer boundaries. A buffer over-read in Util_urlDecode in util.c in Tildeslash Monit before 5.25.3 allows a remote authenticated attacker to retrieve the contents of adjacent memory via manipulation of GET or POST parameters. The attacker can also cause a denial of service (application outage). Affected products include: Tildeslash Monit, Debian Debian Linux, Fedoraproject Fedora, Canonical Ubuntu Linux. Version information: before 5.25.3.

RemediationAI

A vendor patch is available. Apply the latest security update as soon as possible. Validate array indices and buffer lengths. Use memory-safe languages. Enable AddressSanitizer during testing.
