I paketet Net-SNMP, som implementerar protokollen SNMP v1, SNMP v2c och SNMP v3, har en s\u00e5rbarhet (CVE-2025-68615) identifierats, vilket m\u00f6jligg\u00f6r fj\u00e4rrkodexekvering p\u00e5 en server som anv\u00e4nder tj\u00e4nsten snmptrapd f\u00f6r att ta emot och bearbeta trap-meddelanden fr\u00e5n enheter. Som standard tar tj\u00e4nsten emot beg\u00e4rningar p\u00e5 UDP-port 162 och k\u00f6rs med root-r\u00e4ttigheter. Problemet har tilldelats en kritisk riskniv\u00e5 (9,8 av 10). En attack kan utf\u00f6ras utan autentisering. <\/p>\n

S\u00e5rbarheten orsakas av en felaktig kontroll av storleken p\u00e5 OID (\"trapOidLen >= 0\" ist\u00e4llet f\u00f6r \"trapOidLen > 0\") innan de angivna datapaketen kopieras till en fast storleksbuffert. \u00d6verf\u00f6ring av speciellt utformade paket leder till att data skrivs utanf\u00f6r buffern trapOid, vilket kan utnyttjas f\u00f6r att k\u00f6ra kod fr\u00e5n angriparen med de r\u00e4ttigheter som processen snmptrapd k\u00f6rs med. S\u00e5rbarheten har \u00e5tg\u00e4rdats i uppdateringarna av Net-SNMP 5.9.5 och 5.10.pre2. Som ett extra skydd rekommenderas att blockera \u00e5tkomst fr\u00e5n externa n\u00e4tverk till UDP-port 162 i brandv\u00e4ggen.
