CVE-2024-50564 is classified as a low-severity vulnerability affecting Fortinet's FortiClient software. The CVSS score for this vulnerability is 3.3, indicating that while it poses a risk, it is not critical. This vulnerability allows low-privileged users to decrypt interprocess communication via monitoring named pipes due to the use of hard-coded cryptographic keys. Organizations utilizing affected versions should be aware of the potential for unauthorized access to sensitive data.
The urgency for defenders is moderate, as this vulnerability can be exploited under specific conditions. Organizations should prioritize patching as part of their routine maintenance to mitigate risks associated with this issue. While there is no known exploit at this time, the potential for exploitation exists, and organizations are encouraged to remain vigilant.
This vulnerability's impact is primarily related to confidentiality, as it allows unauthorized access to potentially sensitive communication. The attack vector is local, meaning that an attacker must have local access to the system to exploit this vulnerability. Organizations should take proactive steps to safeguard their systems and protect sensitive information.
In summary, CVE-2024-50564 presents a low risk to organizations but should not be disregarded. Regular patching and monitoring of systems are essential to prevent potential exploitation. Organizations that utilize Fortinet FortiClient should include this vulnerability in their security assessments.
Vulnerability Details
The vulnerability is described as a use of hard-coded cryptographic key in Fortinet FortiClient for Windows, affecting versions 7.4.0, 7.2.x (all versions), 7.0.x (all versions), and 6.4.x (all versions). The vulnerability is categorized under CWE-321 (Use of Hard-coded Cryptographic Key) and CWE-798 (Use of Hard-coded Credentials).
The CVSS vector for this vulnerability is CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N, indicating a local attack vector with low complexity and low privileges required. The potential impacts include a low confidentiality impact with no impact on integrity or availability.
Technical Analysis
The root cause of this vulnerability stems from the use of hard-coded cryptographic keys within the FortiClient application. This design flaw enables low-privileged users to monitor and decrypt interprocess communication, thus compromising the confidentiality of potentially sensitive data.
The attack vector is local, meaning that an attacker must have access to the system where FortiClient is installed to exploit this vulnerability. The attack complexity is low, as no special conditions are required for exploitation. The privileges required are also low, allowing unauthorized users to potentially exploit this vulnerability without elevated permissions.
User interaction is not required for this vulnerability to be exploited. The confidentiality impact is categorized as low since attackers may gain access to decrypted communication, but this does not compromise the integrity or availability of the system.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive interprocess communication. The low severity of this vulnerability indicates that while it poses a risk, it is not likely to lead to a significant breach if proper security measures are maintained. However, organizations must assess the potential impact within their environments, especially if sensitive data is transmitted between processes.
The blast radius of this vulnerability is limited to systems running the affected versions of FortiClient. Organizations should consider their deployment of FortiClient and the data being communicated between processes when assessing the risk. Given the low CVSS score and lack of known exploits, the urgency for remediation is categorized as low, and organizations may address this during routine maintenance.
