Summary

The TRUMPF CAD/CAM software tools mentioned above use the vulnerable CodeMeter Runtime (up to version 7.60d) application from WIBU-SYSTEMS AG to manage licenses within the component TRUMPF License Expert. This CodeMeter application contains new vulnerabilities, which may enable an attacker to gain full access to the server or workstation on which the TRUMPF License Expert has been installed on. A new version of the TRUMPF License Expert which fixes these vulnerabilities is available.

Vulnerabilities

Weakness
Out-of-bounds Write (CWE-787)
Summary

This flaw makes curl overflow a heap based buffer in the SOCKS5 proxy handshake. When curl is asked to pass along the host name to the SOCKS5 proxy to allow that to resolve the address instead of it getting done by curl itself, the maximum length that host name can be is 255 bytes. If the host name is detected to be longer, curl switches to local name resolving and instead passes on the resolved address only. Due to this bug, the local variable that means "let the host resolve the name" could get the wrong value during a slow SOCKS5 handshake, and contrary to the intention, copy the too long host name to the target buffer instead of copying just the resolved address there. The target buffer being a heap based buffer, and the host name coming from the URL that curl has been told to operate with.

Weakness
Insufficient Information (NVD-CWE-noinfo)
Summary

Not all valid JavaScript whitespace characters are considered to be whitespace. Templates containing whitespace characters outside of the character set "\t\n\f\r\u0020\u2028\u2029" in JavaScript contexts that also contain actions may not be properly sanitized during execution.

Impact

CVE-2023-24540: According to WIBU, there are no attack vectors for this vulnerability known, so it is said to be not exploitable at present.

Solution

Mitigation

CVE-2023-38545 only appears when used together with a SOCKS-5 Proxy. Not using the
affected products via a SOCKS-5 proxy mitigates the vulnerability.

Remediation
