Technical ContextAI · show details
This vulnerability is classified as Out-of-bounds Read (CWE-125), which allows attackers to read data from memory outside the intended buffer boundaries. In Ashlar-Vellum Cobalt, Xenon, Argon, Lithium, and Cobalt Share versions prior to 12.6.1204.204, the affected applications lack proper validation of user-supplied data when parsing AR files. This could lead to an out-of-bounds read. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process. Affected products include: Ashlar Argon, Ashlar Cobalt, Ashlar Cobalt Share, Ashlar Lithium, Ashlar Xenon. Version information: prior to 12.6.1204.204.

DescriptionCVE.org
In Ashlar-Vellum Cobalt, Xenon, Argon, Lithium, and Cobalt Share versions prior to 12.6.1204.204, the affected applications lack proper validation of user-supplied data when parsing AR files. This could lead to an out-of-bounds read. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process.
Executive ViewAI
CVE-2025-41392 presents notable security risk, a out-of-bounds read vulnerability rated CVSS 8.4. Successful exploitation could significantly impact the confidentiality, integrity, or availability of affected systems. Organizations should apply vendor updates when available and consider compensating controls in the interim.
Apply vendor patch. If immediate patching is not feasible: (1) Implement network-level access controls to limit exposure; (2) Enable enhanced monitoring and alerting; (3) Apply principle of least privilege.

SSVC AssessmentENISA
Priority Score
Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
