CVE-2025-31993 is a Server-Side Request Forgery (SSRF) vulnerability classified under CWE-918, found in HCL Software's Unica Centralized Offer Management product, specifically versions up to 25.1. SSRF vulnerabilities occur when an attacker can manipulate a server-side application to send crafted requests to unintended locations, potentially accessing internal systems or services that are otherwise inaccessible externally. In this case, the vulnerability stems from insufficient input validation, allowing an attacker with high privileges and requiring user interaction to submit malicious input that the server processes. The CVSS 3.1 base score is 3.5, indicating a low severity level, with the vector showing network attack vector (AV:N), low attack complexity (AC:L), but requiring privileges (PR:H) and user interaction (UI:R). The impact is limited to confidentiality (C:L) and availability (A:L), with no integrity impact. No known exploits are currently reported in the wild, and no official patches have been published yet. The vulnerability could allow attackers to make the server perform unauthorized requests, potentially exposing internal resources or causing denial of service conditions. However, exploitation complexity and required privileges reduce the immediate risk. Organizations using Unica Centralized Offer Management should assess their exposure, especially if the application interfaces with sensitive internal networks or services.

For European organizations, the primary impact of this SSRF vulnerability lies in potential unauthorized access to internal network resources and limited disruption of service availability. Since Unica Centralized Offer Management is used for marketing automation and customer engagement, exploitation could lead to leakage of internal service endpoints or limited denial of service, affecting campaign delivery and customer experience. Confidentiality impact is low but could be leveraged in multi-stage attacks to pivot within the network. The requirement for high privileges and user interaction reduces the likelihood of widespread exploitation but does not eliminate risk, especially in environments with insufficient network segmentation or monitoring. Organizations in sectors such as retail, finance, and telecommunications, which heavily rely on customer data and marketing platforms, may face operational disruptions or data exposure risks. The absence of known exploits and patches suggests the threat is currently low but warrants proactive mitigation to prevent escalation.

1. Implement strict input validation and sanitization on all user-supplied data that can influence server-side requests within Unica Centralized Offer Management. 2. Restrict outbound network traffic from the application server to only necessary external endpoints using firewall rules or network segmentation to prevent unauthorized internal resource access. 3. Monitor and log outbound requests from the application for unusual patterns that may indicate SSRF exploitation attempts. 4. Enforce the principle of least privilege for users and services interacting with the application to reduce the risk posed by compromised accounts. 5. Apply network-level protections such as web application firewalls (WAFs) configured to detect and block SSRF attack patterns. 6. Stay updated with HCL Software advisories and apply patches promptly once available. 7. Conduct regular security assessments and penetration testing focusing on SSRF and related vulnerabilities in the application environment. 8. Educate users about the risks of interacting with suspicious content that could trigger SSRF attacks requiring user interaction.
