Cross-Site Scripting in Pilz PASvisu Builder Component

A cross-site scripting vulnerability in the Builder Component of Pilz PASvisu before 1.14.1 allows a local unauthenticated attacker to inject malicious javascript and gain full control over the device.

Casky was already ahead

This CVE exploits attack patterns that Casky's 322matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

CVE-2023-45795 is a high-severity cross-site scripting (XSS) vulnerability affecting Pilz PASvisu versions before 1.14.1, a platform used for industrial automation and safety system visualization. An unauthenticated local attacker can inject malicious JavaScript through the Builder Component, potentially gaining full control of the affected device. This poses significant risk to operational technology (OT) environments where PASvisu is deployed for critical safety functions, as successful exploitation could lead to unauthorized system manipulation, safety system bypass, or cascading failures in connected industrial processes.

Casky's 322 matching skills leverage Claude AI's extended reasoning to detect the attack patterns mapped to MITRE ATT&CK techniques TA0001 (Reconnaissance) and TA0043 (Reconnaissance for Defense Evasion). Practitioners using Casky would identify detection signals across multiple skill categories: input validation failures in the Builder Component parsing logic (CWE-79 manifestation), suspicious JavaScript payloads in application logs, DOM manipulation attempts, and unsafe use of innerHTML or eval() functions. The platform's skills would correlate these technical indicators with the specific application context—highlighting that local access to the Builder interface combined with insufficient input sanitization creates the exploitation chain. Practitioners would see findings that flag both the vulnerability's presence and the reconnaissance behaviors an attacker would employ before executing payload injection, enabling proactive hardening before active exploitation occurs.
