CVE-2009-2548

Status: ModifiedHigh (10)—

Format string vulnerability in Armed Assault (aka ArmA) 1.14 and earlier, and 1.16 beta, and Armed Assault II 1.02 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via format string specifiers in the (1) nickname and (2) datafile fields in a join request, which is not properly handled when logging an error message.

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).
