CVE-2024-47501: Junos OS: MX304, MX with MPC10/11/LC9600, and EX9200 with EX9200-15C: In a VPLS or Junos Fusion scenario specific show commands cause FPCs to crash
First published: Fri Oct 11 2024(Updated: )
A NULL Pointer Dereference vulnerability in the packet forwarding engine (pfe) of Juniper Networks Junos OS on MX304, MX with MPC10/11/LC9600, and EX9200 with EX9200-15C allows a locally authenticated attacker with low privileges to cause a Denial of Service (DoS). In a VPLS or Junos Fusion scenario, the execution of specific show commands will cause all FPCs hosting VPLS sessions or connecting to satellites to crash and restart. This issue affects Junos on MX304, MX with MPC10/11/LC9600 and EX9200 with EX9200-15C: * All version before 21.2R3-S1, * 21.3 versions before 21.3R3, * 21.4 versions before 21.4R2.
