CVE-2023-26293

Status: ModifiedHigh (7.8)—

A vulnerability has been identified in Totally Integrated Automation Portal (TIA Portal) V15 (All versions), Totally Integrated Automation Portal (TIA Portal) V16 (All versions < V16 Update 7), Totally Integrated Automation Portal (TIA Portal) V17 (All versions < V17 Update 6), Totally Integrated Automation Portal (TIA Portal) V18 (All versions < V18 Update 1). Affected products contain a path traversal vulnerability that could allow the creation or overwrite of arbitrary files in the engineering system. If the user is tricked to open a malicious PC system configuration file, an attacker could exploit this vulnerability to achieve arbitrary code execution.

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).
