Title
Ashlar-Vellum Cobalt Uninitialized Memory Remote Code Execution Vulnerability
Summary
Ashlar-Vellum Cobalt Uninitialized Memory 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 CO 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-19878.

Mitigation ID: MIT-57
Phase: Implementation
Strategy: Attack Surface Reduction
Description:
- Ensure that critical variables are initialized before first use [REF-1485].
Mitigation
Phase: Build and Compilation
Strategy: Compilation or Build Hardening
Description:
- Most compilers will complain about the use of uninitialized variables if warnings are turned on.
Mitigation
Phases: Implementation, Operation
Description:
- 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
Phase: Requirements
Strategy: Language Selection
Description:
- Choose a language that is not susceptible to these issues.
Mitigation
Phase: Architecture and Design
Description:
- Mitigating technologies such as safe string libraries and container abstractions could be introduced.
No CAPEC attack patterns related to this CWE.
