Cacti is an open source performance and fault management framework. Due to a flaw in multi-line SNMP result parser, authenticated users can inject malformed OIDs in the response. When processed by ss_net_snmp_disk_io() or ss_net_snmp_disk_bytes(), a part of each OID will be used as a key in an array that is used as part of a system command, causing a command execution vulnerability. This vulnerability is fixed in 1.2.29.

Detection & IOCs extracted from sources · hover to see the quote

• → Vulnerable functions are ss_net_snmp_disk_io() and ss_net_snmp_disk_bytes() — monitor for anomalous or malformed OID values being processed by these Cacti functions, as a portion of the OID is used as an array key in a system command ↗
• → The attack vector is injection of malformed OIDs in multi-line SNMP responses — inspect SNMP poll results ingested by Cacti for unexpected characters or shell metacharacters embedded within OID strings ↗

• · Exploitation requires authentication — prioritize monitoring authenticated Cacti user sessions and restrict SNMP data source permissions to trusted users only ↗
• · Fixed in Cacti 1.2.29 upstream; Debian-specific fixes vary by release (bookworm: 1.2.24+ds1-1+deb12u5, bullseye: 1.2.16+ds1-2+deb11u5, forky/sid/trixie: 1.2.28+ds1-4) — verify the exact installed package version matches the patched version for your distribution ↗
