DescriptionCVE.org

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,

Executive ViewAI

Why It Matters

CVE-2025-52980 is a high-severity denial of service vulnerability affecting an unspecified product with a CVSS score of 7.5, enabling attackers to disrupt service availability. With a vendor patch already available, organizations should prioritize deployment to restore full service resilience, as the 0.1% EPSS score indicates current exploitation risk remains minimal but the vulnerability's impact on uptime justifies immediate attention.

Business Impact: High

Compensating Controls

Apply vendor patch.
