Actively Exploited
CISA Known Exploited Vulnerabilities (KEV) Catalog
EPSS (Exploit Prediction Scoring System) estimates a 3.6% chance this CVE is exploited in the wild within the next 30 days — higher than 89% of all CVEs. It complements CVSS: a high EPSS on a mid-severity CVE can still be urgent.
An improper privilege management vulnerability exists within the Siemens SIMATIC Communication Processor (CP) that allows a privileged attacker to remotely cause a denial of service.
Description
A vulnerability has been identified in SIMATIC CP 1543-1 (All versions < V2.0.28), SIPLUS NET CP 1543-1 (All versions < V2.0.28). Under special conditions it was possible to write SNMP variables on port 161/udp which should be read-only and should only be configured with TIA-Portal. A write to these variables could reduce the availability or cause a denial-of-service.
