Short explanation
CESNET ipfixcol2 versions 2.3.0 through 2.9.0 contain an integer overflow vulnerability in the Forwarder output plugin. Unauthenticated IPFIX exporters can overflow a heap buffer by wrapping uint16_t message length counters.
This vulnerability allows attackers to crash a collector forwarding over TCP and perform 2-byte writes to attacker-influenced addresses. Sources show a slight data conflict regarding the CVSS base score, ranging between 8.3 and 8.2.
What should be done?
- Follow vendor advisories to apply necessary updates
- Upgrade affected deployments to version 2.9.0 or later
- Review official patch commits and references
