medium Nessus Plugin ID 166717

Language:

Description

The remote host is affected by the vulnerability described in GLSA-202210-29 (Net-SNMP: Multiple Vulnerabilities)

 - The vulnerability exists due to a boundary error when handling INDEX of NET-SNMP-VACM-MIB. A remote attacker can trick the victim into loading a specially crafted MIB collection, trigger an out-of-bounds write and execute arbitrary code on the target system. (CVE-2022-24805)

 - The vulnerability exists due to insufficient validation of user-supplied input when SETing malformed OIDs in master agent and subagent simultaneously. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack. (CVE-2022-24806)

 - The vulnerability exists due to a boundary error in a SET request to SNMP-VIEW-BASED-ACM- MIB::vacmAccessTable. A remote user can pass a malformed OID in a SET request, trigger an out-of-bounds write and execute arbitrary code on the target system. (CVE-2022-24807)

 - The vulnerability exists due to a NULL pointer dereference error in NET-SNMP-AGENT-MIB::nsLogTable when handling malformed OID in a SET request. A remote user can pass specially crafted data to the application and perform a denial of service (DoS) attack. (CVE-2022-24808)

 - The vulnerability exists due to a NULL pointer dereference error in nsVacmAccessTable when handling malformed OID in GET-NEXT. A remote user can pass specially crafted data to the application and perform a denial of service (DoS) attack. (CVE-2022-24809)

 - The vulnerability exists due to a NULL pointer dereference error in nsVacmAccessTable when handling malformed OID in a SET request. A remote user can pass specially crafted data to the application and perform a denial of service (DoS) attack. (CVE-2022-24810)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
