Details

Ashlar-Vellum Cobalt VS File Parsing Use of Uninitialized Variable 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 VS files. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25235.

Vulnerability from github – Published: 2025-12-02 03:31 – Updated: 2025-12-02 15:30
VLAI
Details

In display, there is a possible escalation of privilege due to improper input validation. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: ALPS10196993; Issue ID: MSV-4802.

Mitigation MIT-57
Implementation

Strategy: Attack Surface Reduction

Ensure that critical variables are initialized before first use [REF-1485].

Mitigation
Build and Compilation

Strategy: Compilation or Build Hardening

Most compilers will complain about the use of uninitialized variables if warnings are turned on.

Mitigation
Implementation Operation

When using a language that does not require explicit declaration of variables, run or compile the software in a mode that reports undeclared or unknown variables. This may indicate the presence of a typographic error in the variable's name.

Mitigation
Requirements

Strategy: Language Selection

Choose a language that is not susceptible to these issues.

Mitigation
Architecture and Design

Mitigating technologies such as safe string libraries and container abstractions could be introduced.

No CAPEC attack patterns related to this CWE.
