In het Net-SNMP-pakket, dat de protocollen SNMP v1, SNMP v2c en SNMP v3 implementeert, is een kwetsbaarheid (CVE-2025-68615) ontdekt die op afstand code-uitvoering op een server mogelijk maakt die de snmptrapd-service gebruikt voor het ontvangen en verwerken van trap-berichten van apparaten. Standaard accepteert de dienst verzoeken op poort 162 UDP en wordt uitgevoerd met root-rechten. Het probleem heeft een kritieke ernst (9.8 op 10) gekregen. Aanval kan worden uitgevoerd zonder authenticatie. <\/p>\n

De kwetsbaarheid wordt veroorzaakt door een onjuiste controle van de grootte van de OID («trapOidLen >= 0» in plaats van «trapOidLen > 0») voordat de gegevens in het pakket naar een buffer van vaste grootte worden gekopieerd. Het verzenden van speciaal aangepaste pakketten leidt tot het overschrijven van gegevens buiten de trapOid-buffer, wat kan worden misbruikt om aanvallers de mogelijkheid te geven code uit te voeren met de rechten waaronder het proces snmptrapd draait. De kwetsbaarheid is verholpen in de updates van Net-SNMP 5.9.5 en 5.10.pre2. Ter extra bescherming wordt aangeraden de toegang van externe netwerken tot UDP-poort 162 op de firewall te blokkeren.
