TITLE

Out-of-bounds write vulnerabilities in multiple Siemens products

Trust: 0.8

sources: JVNDB: JVNDB-2021-009279

DESCRIPTION

A vulnerability has been identified in JT2Go (All versions < V13.2), Solid Edge SE2021 (All Versions < SE2021MP5), Teamcenter Visualization (All versions < V13.2). The plmxmlAdapterSE70.dll library in affected applications lacks proper validation of user-supplied data when parsing PAR files. This could result in an out of bounds write past the fixed-length heap-based buffer. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-13422). Zero Day Initiative To this vulnerability ZDI-CAN-13422 Was numbering.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.The specific flaw exists within the parsing of PAR files.
