Junos: RPD core due to BGP UPDATE with malformed optional transitive attributes

When the 'bgp-error-tolerance' feature â" designed to help mitigate remote session resets from malformed path attributes â" is enabled, a BGP UPDATE containing a specifically crafted set of transitive attributes can cause the RPD routing process to crash and restart. Devices with BGP enabled that do not have 'bgp-error-tolerance' configured are not vulnerable to this issue. Affected releases are Juniper Networks Junos OS 13.3 prior to 13.3R10-S2; 14.1 prior to 14.1R8-S4, 14.1R9; 14.1X50 prior to 14.1X50-D185; 14.1X53 prior to 14.1X53-D45, 14.1X53-D50; 14.2 prior to 14.2R7-S7, 14.2R8; 15.1 prior to 15.1F5-S8, 15.1F6-S7, 15.1R5-S6, 15.1R6-S2, 15.1R7; 15.1X49 prior to 15.1X49-D100; 15.1X53 prior to 15.1X53-D64, 15.1X53-D70; 16.1 prior to 16.1R3-S4, 16.1R4-S3, 16.1R5; 16.2 prior to 16.2R1-S5, 16.2R2; 17.1 prior to 17.1R1-S3, 17.1R2; 17.2 prior to 17.2R1-S2, 17.2R2; 17.2X75 prior to 17.2X75-D50. No other Juniper Networks products or platforms are affected by this issue.

Remediation

Which version to upgrade to

Fix versions compiled from the vendor, package registries and Microsoft. Verify the vendor's note before upgrading.

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.
