{"id":"CVE-2026-92697","published":"2026-11-05T23:17:02.460","lastModified":"2026-11-05T23:17:02.593","description":"FastNetMon is a high-performance DDoS detector and sensor. In version 1.2.9 and earlier, the NetFlow v9 collector calls  strlen()  on an attacker-controlled interface-description field without bounding the scan to the field’s declared length. Although fields longer than 128 bytes are excluded from this operation, an accepted field without a null terminator can cause reads beyond the field and packet buffer. An unauthenticated remote attacker who can send crafted UDP packets to the collector can trigger an out-of-bounds read and potentially crash the process, causing denial of service. No fixed release is available as of this review.","cvssScore":7.5,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-125"],"vendors":[],"products":[],"references":[{"url":"https://github.com/pavel-odintsov/fastnetmon/commit/9dc766074dc3048ec5007bc3f6a44f2b42d1e1cb","tags":[]},{"url":"https://github.com/pavel-odintsov/fastnetmon/pull/1088","tags":[]},{"url":"https://github.com/pavel-odintsov/fastnetmon/security/advisories/GHSA-ff5f-p5jw-8fq2","tags":[]}],"exploitRefs":[{"url":"https://github.com/pavel-odintsov/fastnetmon/commit/9dc766074dc3048ec5007bc3f6a44f2b42d1e1cb","tags":[]},{"url":"https://github.com/pavel-odintsov/fastnetmon/pull/1088","tags":[]},{"url":"https://github.com/pavel-odintsov/fastnetmon/security/advisories/GHSA-ff5f-p5jw-8fq2","tags":[]}],"hasPoc":true,"ai":null}
