CVE-2025-54967 is an XML External Entity (XXE) vulnerability affecting BAE Systems' SOCET GXP software versions before 4.6.0.3. SOCET GXP is a geospatial analysis and imagery exploitation tool widely used in defense, intelligence, and mapping sectors. The vulnerability arises from improper handling of external entities in certain XML-based files processed by the software. When a user opens a maliciously crafted file containing external entity references, the software processes these entities, triggering outbound network requests. This behavior can be leveraged by an attacker to exfiltrate sensitive information from the victim's environment or perform server-side request forgery (SSRF)-like actions. Exploitation requires social engineering to convince a user to open the malicious file, but no prior authentication or elevated privileges are needed. The CVSS v3.1 base score is 6.5, reflecting medium severity, with a vector indicating network attack vector, low attack complexity, no privileges required, user interaction required, and high confidentiality impact but no integrity or availability impact. The vulnerability is classified under CWE-79 (Improper Neutralization of Input During Web Page Generation), which aligns with injection-type flaws. No patches or exploits are currently publicly available, but the risk remains due to the sensitive nature of data processed by SOCET GXP and the potential for information leakage.

For European organizations, especially those in defense, intelligence, mapping, and geospatial analysis, this vulnerability poses a significant confidentiality risk. SOCET GXP is used by various government agencies and contractors across Europe for sensitive imagery and geospatial data processing. Exploitation could lead to leakage of classified or sensitive operational data, undermining national security and intelligence operations. While the vulnerability does not affect data integrity or system availability, the exposure of sensitive information could have strategic consequences. The requirement for user interaction and social engineering reduces the likelihood of widespread automated exploitation but does not eliminate targeted attacks. Organizations handling critical geospatial intelligence in countries with active defense programs or intelligence sharing agreements are particularly at risk. The lack of known exploits in the wild currently reduces immediate threat levels but should not lead to complacency given the potential impact.

European organizations should implement the following specific mitigations: 1) Immediately update SOCET GXP to version 4.6.0.3 or later once available to address the vulnerability. 2) Until patches are applied, restrict the opening of XML-based files from untrusted or unknown sources and enforce strict file validation policies. 3) Educate users on the risks of social engineering and malicious file handling, emphasizing caution with files received via email or external media. 4) Employ network-level controls to monitor and restrict unexpected outbound requests from SOCET GXP workstations, potentially using application whitelisting or firewall rules to limit external communications. 5) Conduct regular audits of SOCET GXP usage and monitor logs for unusual activity indicative of exploitation attempts. 6) Coordinate with BAE Systems for any interim mitigations or configuration changes that can disable external entity processing if feasible. 7) Integrate SOCET GXP endpoints into broader endpoint detection and response (EDR) solutions to detect suspicious behaviors related to this vulnerability. These steps go beyond generic advice by focusing on user behavior, network controls, and vendor coordination specific to the affected product and threat vector.
