CVE-2023-44452
Published: 03 May 2024
Summary
CVE-2023-44452 is a high-severity Argument Injection (CWE-88) vulnerability in Linuxmint Xreader. Its CVSS base score is 7.8 (High).
Operationally, ranked in the top 4.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
Linux Mint Xreader contains an argument injection vulnerability during CBT file parsing that permits remote code execution. The flaw stems from insufficient validation of a user-supplied string passed to a system call, allowing an attacker-controlled command to be executed. The issue is tracked as ZDI-CAN-22132 and carries a CVSS 3.1 score of 7.8 with the vector AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H; it is also assigned CWE-88.
An unauthenticated attacker can exploit the weakness by supplying a malicious CBT file or hosting content that triggers the parser when the target opens the file or visits the page. Successful exploitation results in arbitrary code execution in the context of the current user, requiring only local access and user interaction.
A patch addressing the issue is available in the Xreader repository at commit cd678889ecfe4e84a5cbcf3a0489e15a5e2e3736, and the Zero Day Initiative published advisory ZDI-23-1836 describing the vulnerability and its resolution.
The associated EPSS score has remained flat at 0.2067 with no material increase since disclosure.

must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of CBT files. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the current user. Was ZDI-CAN-22132.
