30/100

CVSSv3
NA/10

EPSS
0.00079/1

CVE-2024-47494 is a TOCTOU race condition vulnerability in Juniper Networks Junos OS. This flaw in the AgentD process can lead to a denial-of-service (DoS) attack. An attacker, already impacting existing sessions, can trigger AgentD to attempt to access an already destroyed sensor, causing memory corruption and ultimately crashing the FPC (Flexible PIC Concentrator). While the CVSS score is 0, indicating minimal base severity, the SOCRadar Vulnerability Risk Score (SVRS) of 30, combined with the "In The Wild" tag, suggests potential exploitability and a need for monitoring. The FPC recovers automatically after the crash, but service interruption can still occur. It affects multiple Junos OS versions, highlighting the importance of applying available patches to mitigate the vulnerability and prevent potential service disruptions.
