CVE-2024-57493: n/a in n/a
An issue in redoxOS relibc before commit 98aa4ea5 allows a local attacker to cause a denial of service via the setsockopt function.
AI Analysis
Technical Summary
CVE-2024-57493 is a vulnerability identified in the relibc component of redoxOS, an operating system designed with a microkernel architecture and written in Rust. The flaw exists in versions of relibc prior to commit 98aa4ea5 and allows a local attacker to trigger a denial of service (DoS) condition by exploiting the setsockopt function. The setsockopt function is typically used to configure options for sockets, which are endpoints for network communication. The vulnerability is classified under CWE-404, which relates to improper resource shutdown or release, indicating that the issue likely involves mishandling of resources during socket option configuration, leading to system instability or crash. The CVSS v3.1 base score is 5.5 (medium severity), with the vector AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H, meaning the attack requires local access with low privileges, no user interaction, and results in a high impact on availability without affecting confidentiality or integrity. No known exploits are currently reported in the wild, and no patches are linked yet, suggesting this is a recently discovered vulnerability. The vulnerability affects local users who can execute code or commands on the system, potentially causing denial of service by crashing or halting critical system components through malformed setsockopt calls. Given redoxOS's niche usage primarily in research, development, or specialized environments, the scope of affected systems is limited compared to mainstream operating systems. However, the vulnerability could be leveraged in multi-user or shared environments to disrupt services or system availability.
Potential Impact
For European organizations, the impact of CVE-2024-57493 is likely limited due to the relatively low adoption of redoxOS in commercial or critical infrastructure environments. However, organizations involved in research, development, or those experimenting with alternative operating systems might be affected if they use vulnerable versions of relibc. The primary impact is denial of service, which could disrupt operations on affected machines, potentially affecting development workflows or testing environments. Since the vulnerability requires local access with low privileges, the risk increases in environments where multiple users have shell or command access, such as academic institutions or collaborative research centers. The lack of impact on confidentiality and integrity reduces the risk of data breaches or unauthorized data modification. Nonetheless, availability disruptions could delay projects or cause downtime in experimental setups. Given the medium severity and local attack vector, the threat to broader European critical infrastructure or large enterprises is minimal at this time.
Mitigation Recommendations
To mitigate CVE-2024-57493, European organizations using redoxOS or relibc should: 1) Monitor official redoxOS repositories and security advisories for patches or updates addressing this vulnerability and apply them promptly once available. 2) Restrict local user access on systems running redoxOS to trusted personnel only, minimizing the risk of exploitation by unprivileged users. 3) Implement strict access controls and user privilege management to prevent unauthorized local access, especially in multi-user environments. 4) Employ system monitoring and logging to detect unusual or repeated calls to setsockopt that could indicate attempted exploitation. 5) Consider isolating vulnerable systems or running them in sandboxed environments to limit the impact of a potential denial of service. 6) For development or research environments, maintain regular backups and ensure rapid recovery procedures to minimize downtime caused by potential crashes. These steps go beyond generic advice by focusing on access control, monitoring, and isolation tailored to the local attack vector and denial of service impact.
