CVE-2025-29008 is a Server-Side Request Forgery (SSRF) vulnerability identified in ShawonPro's SocialMark product, affecting versions up to 2.0.7. SSRF vulnerabilities occur when an attacker can manipulate a server to make unintended HTTP requests to internal or external systems. In this case, the vulnerability allows an attacker with low privileges (PR:L) and no user interaction (UI:N) to coerce the SocialMark server into sending crafted requests to arbitrary URLs. The CVSS 3.1 base score is 4.9 (medium severity), reflecting that exploitation requires network access and low privileges, with high attack complexity. The vulnerability impacts confidentiality and integrity, as attackers may access internal resources or manipulate data via forged requests, but does not affect availability. The scope is changed (S:C), indicating that the vulnerability can affect components beyond the initially vulnerable module. No known exploits are currently reported in the wild, and no patches have been published yet. The lack of patch links suggests that mitigation is currently limited to workaround or configuration changes. SSRF vulnerabilities are particularly dangerous because they can be used to bypass firewall restrictions, access internal services, or escalate attacks within a network. Given SocialMark is a social media marketing tool, it likely interacts with various web services and APIs, increasing the attack surface for SSRF exploitation.

For European organizations using ShawonPro SocialMark, this SSRF vulnerability poses a risk of unauthorized internal network reconnaissance and potential data leakage. Attackers could leverage SSRF to access internal-only services, such as metadata APIs, internal databases, or administrative interfaces, potentially leading to further compromise. Confidentiality is at risk as sensitive internal information could be exposed. Integrity could be impacted if the attacker uses SSRF to manipulate internal services or data. Although availability is not directly affected, the indirect consequences of successful exploitation could disrupt business operations. Organizations in sectors with strict data protection regulations, such as finance, healthcare, and government, could face compliance issues if internal data is exposed. The medium severity score suggests that while the vulnerability is not trivial to exploit, it still requires attention to prevent potential lateral movement or data breaches within corporate networks.

Since no official patches are currently available, European organizations should implement immediate mitigations to reduce risk. These include: 1) Restricting outbound HTTP requests from the SocialMark server to only trusted domains and IP ranges using network-level controls such as firewall rules or proxy whitelisting. 2) Implementing input validation and sanitization on any user-controllable parameters that influence URL requests within SocialMark to prevent injection of arbitrary URLs. 3) Monitoring and logging outbound requests from SocialMark for unusual or unexpected destinations to detect potential exploitation attempts. 4) Segmenting the network to isolate SocialMark servers from sensitive internal resources, limiting the impact of SSRF exploitation. 5) Applying the principle of least privilege to the SocialMark service account to minimize access to internal systems. 6) Staying alert for vendor updates or patches and applying them promptly once available. 7) Conducting internal security assessments or penetration tests focusing on SSRF vectors in SocialMark deployments to identify and remediate weaknesses proactively.
