CVE-2008-1749

Status: ModifiedHigh (7.8)—

Memory leak in Cisco Content Switching Module (CSM) 4.2(3) up to 4.2(8) and Cisco Content Switching Module with SSL (CSM-S) 2.1(2) up to 2.1(7) allows remote attackers to cause a denial of service (memory consumption) via TCP segments with an unspecified combination of TCP flags.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
