Base vector

AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions: JT2Go versions prior to V13.2 Solid Edge SE2021 versions prior to SE2021MP5 Teamcenter Visualization versions prior to V13.2

Description: A vulnerability has been identified in the specified software versions. The plmxmlAdapterSE70.dll library lacks proper validation of user-supplied data when parsing PAR files, which could result in an out of bounds write past the fixed-length heap-based buffer. This could allow an attacker to execute code in the context of the current process.

Recommendations: For JT2Go versions prior to V13.2, update to version V13.2 or later. For Solid Edge SE2021 versions prior to SE2021MP5, update to version SE2021MP5 or later. For Teamcenter Visualization versions prior to V13.2, update to version V13.2 or later. As a temporary workaround, consider restricting the use of the plmxmlAdapterSE70.dll library until a patch is available.
