All releases of Cisco IOS Software from 15.2(5a)E up to 15.2(7)E12 (including ) on the Catalyst 2960L switches are affected by a vulnerability in the Access Control List (ACL) programming (CVE-2025-20137). This vulnerability could allow an unauthenticated, remote attacker to bypass a configured ACL. The issue arises from the unsupported combination of an IPv4 ACL and a dynamic ACL of IP Source Guard on the same interface. Cisco has updated documentation to reflect that this is an unsupported configuration.
Powering multiple high-draw Power-over-Ethernet (PoE/PoE+) devices significantly increases the internal temperature of the integrated power supply unit (PSU).
