CVE-2024-45165 identifies a cryptographic weakness in UCI IDOL 2 (also known as uciIDOL or IDOL2) versions up to 2.12, where the encryption key for securing data transmitted between client and server is derived from a static, hardcoded string: "(c)2007 UCI Software GmbH B.Boll". This key derivation method violates cryptographic best practices by using a constant, publicly known string as the basis for encryption keys, effectively rendering the encryption trivial to break for anyone who can capture the network traffic. As a result, an attacker with access to the communication channel can decrypt intercepted messages and also forge encrypted messages, enabling both passive eavesdropping and active man-in-the-middle (MITM) attacks. The vulnerability is classified under CWE-798 (Use of Hard-coded Credentials), highlighting the risk of embedding fixed secrets in code. The CVSS v3.1 base score is 5.3 (medium severity), reflecting the attack vector as adjacent network (AV:A), high attack complexity (AC:H), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), but no impact on integrity (I:N) or availability (A:N). No patches or fixes have been published yet, and no exploits are currently known in the wild. This vulnerability primarily threatens the confidentiality of data exchanged via UCI IDOL 2, which may include sensitive or proprietary information depending on the deployment context.

The primary impact of CVE-2024-45165 is the compromise of confidentiality for data transmitted between clients and servers using UCI IDOL 2. Attackers capable of intercepting network traffic can decrypt sensitive information, potentially exposing intellectual property, personal data, or other confidential communications. Additionally, the ability to encrypt messages allows an attacker to perform active MITM attacks, injecting or modifying data in transit without detection. This undermines trust in the communication channel and can lead to further exploitation or data manipulation downstream. While integrity and availability are not directly impacted, the breach of confidentiality alone can have severe consequences for organizations, including regulatory non-compliance, reputational damage, and operational risks. The attack complexity is high, requiring network access to the communication channel, which may limit exposure to local or adjacent network attackers rather than remote internet-based adversaries. However, in environments where UCI IDOL 2 is used internally or across trusted networks, the risk remains significant. The absence of patches means organizations must rely on compensating controls until a fix is available.

Given the lack of available patches for CVE-2024-45165, organizations should implement several specific mitigations: 1) Restrict network access to UCI IDOL 2 communication channels by using network segmentation, firewalls, and VPNs to limit exposure to trusted hosts only. 2) Employ network-level encryption or tunneling (e.g., TLS, IPsec) external to the application to protect data in transit independently of the vulnerable encryption. 3) Monitor network traffic for unusual patterns or signs of MITM attacks, including unexpected message modifications or repeated retransmissions. 4) Conduct regular security audits and penetration tests focusing on the UCI IDOL 2 environment to detect potential exploitation attempts. 5) Engage with the vendor or software maintainers to obtain updates or patches addressing the hardcoded key issue. 6) Where feasible, replace or upgrade UCI IDOL 2 deployments with alternative solutions that follow secure cryptographic practices. 7) Educate network administrators and security teams about this vulnerability to ensure rapid detection and response. These targeted actions go beyond generic advice by focusing on network controls and compensating encryption layers to mitigate the specific risk posed by the static key.
