CVE-2024-54661 is classified as a critical vulnerability affecting Socat, specifically the readline.sh script in versions before 1.8.0.2. This vulnerability allows unauthorized access to sensitive files due to reliance on a predictable temporary file path, /tmp/$USER/stderr2. With a CVSS score of 9.8, the severity of this vulnerability is high, indicating a significant risk to organizations that utilize Socat.
Given its high CVSS score, the urgency for organizations to address this vulnerability cannot be overstated. Attackers may leverage this vulnerability to overwrite critical files, leading to potential data loss or system compromise. Organizations should prioritize patching immediately to safeguard their systems.
As of now, there are no confirmed public exploits or proof-of-concept codes available for this vulnerability, but its critical nature necessitates proactive measures. Organizations using affected versions should prepare for possible future exploitation attempts as the vulnerability gains visibility.
Immediate action is crucial for all organizations using Socat. Ensure systems are updated to the latest version to mitigate any risks associated with this vulnerability.
Vulnerability Details
The official description of CVE-2024-54661 states that readline.sh in Socat before version 1.8.0.2 relies on the /tmp/$USER/stderr2 file, which can be exploited for arbitrary file overwrite.
This vulnerability is classified under CWE-61, which pertains to the use of hard-coded sensitive information. The CVSS score of 9.8 places this vulnerability in the critical severity category, highlighting the immediate need for remediation.
The vulnerability was published on December 4, 2024, and has not been assigned a known exploitation status in the KEV database.
Technical Analysis
The root cause of this vulnerability stems from the reliance on a predictable file path that is accessible to unauthorized users. The attack vector is network-based with low complexity, meaning that an attacker does not need advanced skills to exploit this vulnerability. Importantly, no privileges are required, and user interaction is not necessary for the attack to succeed.
The potential impacts of this vulnerability are significant: a high impact on confidentiality, integrity, and availability of the affected systems. This means that an attacker could potentially read sensitive information, modify files, or disrupt services.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive files, potential data loss, and system disruptions. Given the critical nature of this vulnerability, attackers may actively target systems running vulnerable versions of Socat, increasing the urgency for remediation.
Organizations should assess their exposure to this vulnerability and prioritize updates as part of their security patch management processes. The potential blast radius of an exploit could significantly affect organizational operations, justifying immediate action.
