CVE-2019-4687

Vulnerability

IBM Guardium Data Encryption (GDE) version 3.0.0.2 stores sensitive information in URL parameters [1]. This vulnerability exists in the web interface of the product, where confidential data such as session tokens or other credentials may be inadvertently exposed in the URL. The affected version is GDE 3.0.0.2 [1].

Exploitation

An attacker does not require any special privileges to exploit this vulnerability; they only need access to locations where URLs are recorded, such as server access logs, HTTP referrer headers sent to third-party sites, or browser history. No user interaction beyond normal browsing is needed, and the attacker does not need to be authenticated to the system [1].

Impact

Successful exploitation allows an attacker to read the sensitive information contained in the URLs. This leads to information disclosure, potentially compromising user credentials, session identifiers, or other confidential data. The confidentiality of the system is impacted, though integrity and availability are not directly affected [1].

Mitigation

IBM has not released a specific fix for CVE-2019-4687 in the referenced security bulletin. The bulletin [1] addresses other vulnerabilities in GDE but does not provide a patch or workaround for this particular issue. Users should monitor IBM's support page for future updates. As a general practice, avoid passing sensitive data in URL parameters.
