oFono AT CMGL Command Uninitialized Variable Information Disclosure Vulnerability

Noroxi assessment

Priority: Monitor (action score 13/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.29% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: ofono (Debian:13) 2.14-1; ofono (openSUSE:Leap 16.0) 2.19-bp160.1.1; ofono (openSUSE:Tumbleweed) 2.19-3.1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to ofono (Debian:13) 2.14-1; ofono (openSUSE:Leap 16.0) 2.19-bp160.1.1; ofono (openSUSE:Tumbleweed) 2.19-3.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

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 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.
