Summary

CVE-2024-7540 is a low-severity Use of Uninitialized Variable (CWE-457) vulnerability in Ofono Project Ofono. Its CVSS base score is 3.3 (Low).

Operationally, exploitation aligns with the MITRE ATT&CK technique OS Credential Dumping (T1003); ranked at the 22th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-15 (Development Process, Standards, and Tools) — see the control section below for these in your framework.

Vulnerability Data

oFono AT CMGL 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…

more

exploit this vulnerability. The specific flaw exists within the parsing of responses from AT+CMGL 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-23307.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and static analysis directly find uses of uninitialized variables before deployment.

Documented development standards and tools can enforce initialization requirements in code.

Engineering principles can mandate explicit variable initialization to avoid uninitialized use.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly catch uninitialized-variable defects via static analysis and code review while the control encompasses many additional development controls.

finds

Security testing can detect uninitialized-variable bugs, but the control is broader.

prevents

Secure development life cycle mandates practices that reduce uninitialized-variable defects.

prevents

Application security requirements can specify initialization rules, but the control itself does not directly address the weakness.

prevents

Secure system architecture and engineering principles include defensive coding practices that prevent use of uninitialized memory or objects.

prevents

Secure coding explicitly requires variable initialization and static-analysis checks.
