This critical-severity CVE scores 9.6 under NVD CVSS v3. EPSS exploit probability: 1.0%, top 41% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

A vulnerability has been identified in SICAM WEB firmware for SICAM A8000 RTUs (All versions < V05.30). The login screen does not sufficiently sanitize input, which enables an attacker to generate specially crafted log messages. If an unsuspecting victim views the log messages via the web browser, these log messages might be interpreted and executed as code by the web application. This Cross-Site-Scripting (XSS) vulnerability might compromize the confidentiality, integrity and availability of the web application.
