CVE-2022-37706 is a high-severity privilege escalation vulnerability affecting Enlightenment versions prior to 0.25.4. This vulnerability allows local users to gain privileges because the enlightenment_sys component is setuid root. The underlying system library function mishandles pathnames that begin with a /dev/.. substring, creating a potential attack vector for local users.
The CVSS score for this vulnerability is 7.8, which classifies it as high severity. This score indicates a significant risk, particularly as it entails high confidentiality, integrity, and availability impacts. Organizations must understand the importance of addressing this issue promptly to secure their systems.
Currently, there is no known active exploitation of this vulnerability in the wild. However, given the ease of exploitation and high potential impact, organizations should prioritize remediation efforts as part of their security best practices.
Organizations should prioritize patching immediately to mitigate risks associated with CVE-2022-37706. The potential for local users to gain elevated privileges poses a serious threat to system integrity and security. As such, it is critical to act swiftly in validating and implementing the necessary security updates.
Vulnerability Details
The official description of CVE-2022-37706 states that the vulnerability allows local users to gain privileges due to improper handling of pathnames by the enlightenment_sys component in Enlightenment versions prior to 0.25.4. The affected component has been assigned the CWE ID CWE-269, indicating a privilege escalation vulnerability.
The CVSS v3.1 vector string is CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, with a base score of 7.8. This score reflects a local attack vector with low complexity, low privileges required, and no user interaction necessary. The impact on confidentiality, integrity, and availability is rated as high.
This vulnerability was published on December 25, 2022, and has been marked as modified since then. Organizations using the affected version of Enlightenment should act quickly to apply the necessary updates.
Technical Analysis
The root cause of CVE-2022-37706 lies in the setuid configuration of the enlightenment_sys component combined with improper pathname handling. This creates a scenario where a local user can exploit the vulnerability to execute arbitrary code with elevated privileges.
The attack vector is classified as local, meaning that an attacker must have access to the local system to exploit the vulnerability. The complexity is low, indicating that an attacker can exploit this vulnerability without advanced skills. Privileges required are also low, allowing a user with minimal rights to perform the attack. There is no user interaction required for the exploitation.
The potential impact of this vulnerability is high across confidentiality, integrity, and availability, which means successful exploitation could lead to significant damage to the affected system.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2022-37706 is substantial. Given that it allows local users to elevate their privileges, the blast radius is potentially significant. Attackers could exploit this vulnerability to gain unauthorized access to sensitive data, execute malicious code, or compromise system integrity.
Organizations should assess their exposure based on the CVSS score and the potential impact of the vulnerability. The urgency of remediation is high, and organizations must address this vulnerability in their patch management cycles to reduce the risk of exploitation.
As local attacks may be easier to initiate, it is imperative for organizations to ensure that their local environments are secure. Failure to patch this vulnerability could lead to severe security incidents.
