A vulnerability in the Border Gateway Protocol (BGP) processing functionality of the Cisco StarOS operating system for Cisco ASR 5000 Series

A vulnerability in the Border Gateway Protocol (BGP) processing functionality of the Cisco StarOS operating system for Cisco ASR 5000 Series Routers and Cisco Virtualized Packet Core (VPC) Software could allow an unauthenticated, remote attacker to cause the BGP process on an affected system to reload, resulting in a denial of service (DoS) condition. This vulnerability affects the following products if they are running the Cisco StarOS operating system and BGP is enabled for the system: Cisco ASR 5000 Series Routers and Cisco Virtualized Packet Core Software. More Information: CSCvc44968. Known Affected Releases: 16.4.1 19.1.0 21.1.0 21.1.M0.65824. Known Fixed Releases: 21.3.A0.65902 21.2.A0.65905 21.1.b0.66164 21.1.V0.66014 21.1.R0.65898 21.1.M0.65894 21.1.0.66030 21.1.0.

No fix version is recorded for this entry. Check the references for vendor advisories.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
