CVE-2022-40765 is a medium-severity vulnerability affecting the Edge Gateway component of Mitel MiVoice Connect, specifically through version 19.3 (22.22.6100.0). This vulnerability allows an authenticated attacker with internal network access to conduct a command-injection attack due to insufficient restriction of URL parameters. The risk posed by this vulnerability is significant, as it could lead to unauthorized command execution within the system.
With a CVSS score of 6.8, the vulnerability falls into the medium severity category. The attack vector is classified as adjacent network, suggesting that an attacker must have some form of access to the internal network to exploit this vulnerability. Given the potential impact on confidentiality, integrity, and availability, organizations using the affected product must act swiftly to address this issue.
As of now, there is no known public exploit for CVE-2022-40765. However, it is crucial for security teams to remain vigilant, as the presence of a command injection vulnerability could lead to serious repercussions if exploited. Organizations should prioritize patching this vulnerability to prevent potential exploitation.
Organizations should prioritize patching immediately. Timely remediation is essential to mitigate risks associated with this vulnerability.
Vulnerability Details
The official description of the vulnerability states that it exists in the Edge Gateway component of Mitel MiVoice Connect through version 19.3 (22.22.6100.0). This vulnerability allows an authenticated attacker with internal network access to conduct a command-injection attack due to insufficient restriction of URL parameters. The vulnerability is classified under CWE-77, indicating that it relates to improper neutralization of special elements used in a command. The CVSS score of 6.8 indicates a medium severity level, highlighting the importance of addressing this issue promptly.
Technical Analysis
The root cause of CVE-2022-40765 is insufficient validation of URL parameters within the Edge Gateway component, which leads to the potential for command injection. This vulnerability can be exploited over an adjacent network, requiring high privileges to execute the attack. The attack complexity is low, meaning that an attacker with the necessary access could exploit this vulnerability with minimal effort. Importantly, user interaction is not required for exploitation, making it easier for attackers to leverage this vulnerability.
If exploited, the impacts include high confidentiality, integrity, and availability risks. Attackers may leverage this vulnerability to execute arbitrary commands within the context of the system, leading to potential data breaches or service disruptions.
Risk & Impact Analysis
The risk to organizations includes unauthorized command execution, which could compromise sensitive data and disrupt services. Given that the vulnerability is exploitable by authenticated users with internal network access, the blast radius could be significant in environments where users have elevated privileges. Organizations must assess their internal access controls and monitor for any unauthorized activities in relation to this vulnerability. Based on the CVSS score, immediate action is required to patch or mitigate this vulnerability.
