The sctp_send_initiate_ack function in sys/netinet/sctp_output.c in the SCTP implementation in the kernel in FreeBSD 8.3 through 9.2-PRERELEASE does not properly initialize the state-cookie data structure, which allows remote attackers to obtain sensitive information from kernel stack memory by reading packet data in INIT-ACK chunks.

Security readout for executives and security teams

CVE-2013-5209 is a FreeBSD kernel information disclosure flaw in SCTP. A remote attacker could receive uninitialized kernel stack data inside SCTP INIT-ACK packets. This may expose sensitive memory contents, but the provided sources do not show code execution, active exploitation, or a CVSS score. Exposure is most likely on FreeBSD 8.3 through 9.2-PRERELEASE systems where SCTP traffic can reach the host. Systems not running affected FreeBSD versions, or not reachable over SCTP, are less likely exposed based on the provided evidence. Treat this as a legacy FreeBSD exposure review. It is not listed as known exploited, but remote kernel memory disclosure can aid further attacks. Prioritize internet-facing or untrusted-network FreeBSD systems first, especially unsupported versions. Mitigation focus: Identify FreeBSD systems in the affected version range.; Review and apply FreeBSD-SA-13:10 vendor guidance.; Upgrade to a fixed FreeBSD release or vendor-supported branch where applicable..
