CVE-2025-14811 identifies a vulnerability in IBM Sterling Partner Engagement Manager versions 6.2.3.0 through 6.2.3.5 and 6.2.4.0 through 6.2.4.2, where sensitive information is transmitted via HTTP GET request query strings. The core issue is the use of the GET method to send sensitive data, which inherently exposes this data in URLs. Since URLs can be logged in various places such as browser history, proxy logs, and server logs, and are also visible in transit if encryption is not enforced, attackers positioned to perform man-in-the-middle (MITM) attacks can intercept these query strings and extract sensitive information. The vulnerability is classified under CWE-598, which concerns the use of GET requests with sensitive query strings. The CVSS v3.1 base score is 3.1, indicating low severity, with attack vector network (AV:N), high attack complexity (AC:H), low privileges required (PR:L), no user interaction (UI:N), and impact limited to confidentiality (C:L) without affecting integrity or availability. No patches or exploits are currently known, but the vulnerability highlights insecure design choices in handling sensitive data within URLs rather than in request bodies or headers. This can lead to unintended information disclosure especially in environments where encrypted transport (e.g., HTTPS) is not strictly enforced or where network traffic can be intercepted.

The primary impact of this vulnerability is the potential disclosure of sensitive information to unauthorized parties via interception of HTTP GET request query strings. This can lead to confidentiality breaches, potentially exposing credentials, tokens, or other sensitive parameters embedded in URLs. While the vulnerability does not affect data integrity or system availability, the exposure of sensitive data can facilitate further attacks such as session hijacking, unauthorized access, or information leakage that undermines organizational security. Organizations relying on IBM Sterling Partner Engagement Manager in affected versions may face increased risk if their network communications are not fully encrypted or if attackers have the capability to perform MITM attacks. The impact is limited by the requirement for network access and the high complexity of the attack, but the sensitivity of the data exposed could have regulatory and reputational consequences, especially in industries handling sensitive partner or transactional data.

To mitigate this vulnerability, organizations should first ensure that all communications with IBM Sterling Partner Engagement Manager are conducted over encrypted channels such as TLS/HTTPS to prevent interception of query strings. Network security controls should be implemented to detect and prevent MITM attacks, including the use of strong certificate validation and network segmentation. Review and refactor application logic to avoid placing sensitive information in URL query parameters; instead, use POST requests with parameters in the request body or secure headers. Monitor and audit logs to detect any unusual access patterns or data leakage. If possible, upgrade to versions of the product that do not exhibit this vulnerability once patches become available. Additionally, educate developers and administrators on secure coding practices regarding sensitive data transmission and enforce strict access controls to limit exposure. Employ web application firewalls (WAFs) to detect and block suspicious requests that may attempt to exploit this vulnerability.
