Vulnerability from github – Published: 2024-08-06 00:31 – Updated: 2024-08-06 00:31oFono AT CMT Command Uninitialized Variable Information Disclosure Vulnerability. This vulnerability allows local attackers to disclose sensitive information on affected installations of oFono. An attacker must first obtain the ability to execute code on the target modem in order to exploit this vulnerability.
The specific flaw exists within the parsing of responses from AT+CMT commands. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root. Was ZDI-CAN-23308.

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