CVE-2025-52980

A Use of Incorrect Byte Ordering

vulnerability

in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS on SRX300 Series allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS).

When a BGP update is received over an established BGP session which contains a specific, valid, optional, transitive path attribute, rpd will crash and restart.

This issue affects eBGP and iBGP over IPv4 and IPv6.

This issue affects:

Junos OS:

• 22.1 versions from 22.1R1 before 22.2R3-S4,
• 22.3 versions before 22.3R3-S3,
• 22.4 versions before 22.4R3-S2,
• 23.2 versions before 23.2R2,
• 23.4 versions before 23.4R2.

Weakness

The product receives input from an upstream component, but it does not account for byte ordering (e.g. big-endian and little-endian) when processing the input, causing an incorrect number or value to be used.
