Security News > 2024 > February > Critical Cisco bug exposes Expressway gateways to CSRF attacks
Cisco has patched several vulnerabilities affecting its Expressway Series collaboration gateways, two of them rated as critical severity and exposing vulnerable devices to cross-site request forgery attacks.
Unauthenticated attackers can exploit the two critical CSRF vulnerabilities patched today to target unpatched Expressway gateways remotely.
CVE-2024-20254 and CVE-2024-20255 impact Cisco Expressway Series devices with default configurations, while CVE-2024-20252 can only be exploited to attack gateways where the cluster database API feature has been toggled on.
Last month, Cisco warned of a critical severity remote code execution flaw impacting its Unified Communications Manager and Contact Center Solutions products after patching a severe Unity Connection bug that could let unauthenticated attackers gain root privileges remotely.
