CVE-2023-34300

Estado: AnalizadaAlta (7.8)—

Ashlar-Vellum Cobalt XE File Parsing Untrusted Pointer Dereference Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ashlar-Vellum Cobalt. 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 XE files. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to execute code in the context of the current process. . Was ZDI-CAN-17948.
