Description

CVE-2024-48208 is a vulnerability in the pure-ftpd software, specifically versions prior to 1.0.52. This vulnerability stems from a buffer overflow flaw in the domlsd() function within the ls.c file, leading to an out-of-bounds read condition. This vulnerability could allow attackers to potentially execute arbitrary code on a vulnerable system.

While the CVSS score is 8.6, indicating a high severity, the SOCRadar Vulnerability Risk Score (SVRS) is 30, signifying a moderate risk level. This suggests that although the vulnerability is serious, it may not be actively exploited by threat actors at this time. However, given the "In The Wild" tag, it's crucial to take immediate action to mitigate this threat.

Key Insights

• Exploit Status: This vulnerability is "In The Wild," meaning that attackers are actively exploiting this vulnerability in real-world attacks.
• Threat Actors/APT Groups: While specific threat actors or APT groups have not been publicly identified as exploiting this vulnerability, the fact it's "In The Wild" implies that various malicious actors may be leveraging this vulnerability for their gains.
• Code Impact: The vulnerability resides within the domlsd() function, which is responsible for listing directories. This means that attackers could potentially gain access to sensitive files and information if the vulnerability is successfully exploited.
• Impact: Successful exploitation of this vulnerability could lead to complete system compromise. Attackers could potentially gain control over the affected system, allowing them to install malware, steal data, or launch further attacks.

Mitigation Strategies

1. Upgrade to the Latest Version: The most effective mitigation strategy is to upgrade to pure-ftpd version 1.0.52 or later. This update addresses the vulnerability and prevents future exploitation.
2. Disable or Restrict Access to the Vulnerable Function: If immediate upgrading is not feasible, consider disabling or restricting access to the domlsd() function. This can be done through configuration settings or by implementing network access controls.
3. Implement Network Segmentation: Segmenting your network can limit the potential impact of the vulnerability by isolating the affected systems. This helps to contain any potential breaches and prevent attackers from gaining access to other critical resources.
4. Regular Security Monitoring: Implement robust security monitoring practices, including intrusion detection systems (IDS) and security information and event management (SIEM) tools. These systems can help detect suspicious activity and alert you to potential attacks.
