CVE-2024-0350 is a security vulnerability identified in SourceCodester Engineers Online Portal version 1.0. The vulnerability is classified under CWE-613, which pertains to improper session expiration. Specifically, this issue involves a flaw in the session management mechanism where sessions may expire prematurely or unexpectedly due to manipulation of an unspecified functionality. The vulnerability can be exploited remotely, but the attack complexity is rated as high, indicating that exploitation requires significant effort or specific conditions. No user interaction is needed, and the attacker requires low privileges to attempt exploitation. The CVSS v3.1 base score is 3.1, categorizing it as a low-severity issue. The impact primarily affects the integrity of the session state, potentially disrupting legitimate user sessions by forcing expiration. Confidentiality and availability are not impacted, and no known exploits are currently active in the wild. The vulnerability disclosure is public, but no patches or fixes have been linked yet. The lack of detailed technical information about the exact manipulation vector limits the depth of analysis, but the core issue revolves around session lifecycle management and its improper handling, which could lead to denial of service for legitimate users or session management inconsistencies.

For European organizations using the SourceCodester Engineers Online Portal 1.0, this vulnerability could result in unexpected session terminations, disrupting normal workflow and user experience. Although the severity is low and does not directly compromise data confidentiality or system availability, the integrity of user sessions is affected, which could lead to operational inefficiencies and user frustration. In environments where continuous session availability is critical, such as engineering project management or collaboration platforms, this could indirectly impact productivity. Since the attack complexity is high and no known exploits are in the wild, the immediate risk is limited. However, organizations relying on this portal should be aware of potential session management issues that could be exploited by attackers with some level of access, possibly leading to denial of service conditions or forcing users to re-authenticate frequently.

Given the nature of the vulnerability, organizations should implement the following specific mitigations: 1) Monitor session management behavior closely to detect abnormal session expirations or patterns indicative of manipulation attempts. 2) Enforce strict session timeout policies and validate session tokens server-side to prevent unauthorized session termination. 3) If possible, upgrade to a newer version of the software or apply vendor patches once available. 4) Implement additional logging around session lifecycle events to facilitate forensic analysis if exploitation is suspected. 5) Restrict access to the portal to trusted networks or VPNs to reduce exposure to remote attacks. 6) Educate users to report unexpected logouts promptly to IT security teams. 7) Consider deploying web application firewalls (WAFs) with custom rules to detect and block suspicious session-related requests targeting the portal. These measures go beyond generic advice by focusing on session management monitoring, access restriction, and proactive detection tailored to this vulnerability's characteristics.
