CVE-2024-25301 is a high-severity remote code execution (RCE) vulnerability identified in Redaxo version 5.15.1, specifically within the /pages/templates.php component. Redaxo is a content management system (CMS) used for website management and development. The vulnerability is classified under CWE-94, which relates to improper control of code generation, indicating that the flaw likely involves unsafe handling or execution of user-supplied input that leads to arbitrary code execution on the server. The CVSS 3.1 base score of 7.2 reflects a high severity, with the vector indicating that the attack can be performed remotely over the network (AV:N) with low attack complexity (AC:L), but requires high privileges (PR:H) and no user interaction (UI:N). The scope is unchanged (S:U), and the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). Although no specific vendor or product details beyond the Redaxo version are provided, the vulnerability allows an attacker with elevated privileges to execute arbitrary code remotely, potentially leading to full system compromise, data theft, or service disruption. No public exploits are currently known, and no patches or mitigation links have been published yet, which may indicate that the vulnerability is newly disclosed and under active analysis or remediation by the vendor.

For European organizations using Redaxo CMS version 5.15.1, this vulnerability poses a significant risk. Successful exploitation could allow attackers to execute arbitrary code remotely, leading to unauthorized access to sensitive data, defacement or manipulation of web content, disruption of services, or use of compromised servers as a foothold for further attacks within the network. Given the high impact on confidentiality, integrity, and availability, organizations handling personal data under GDPR could face compliance violations and reputational damage. The requirement for high privileges to exploit the vulnerability suggests that attackers would need to first gain elevated access, possibly through other vulnerabilities or credential compromise, but once achieved, the risk is critical. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate it, especially as threat actors may develop exploits rapidly after public disclosure. European organizations relying on Redaxo for public-facing websites or internal portals should consider this vulnerability a priority for investigation and remediation.

1. Immediate assessment of Redaxo CMS installations to identify any running version 5.15.1, particularly focusing on the /pages/templates.php component. 2. Restrict access to the CMS backend to trusted IP addresses and enforce strong authentication mechanisms, including multi-factor authentication, to reduce the chance of privilege escalation. 3. Monitor logs for unusual activity or attempts to access the vulnerable component, especially from external sources. 4. Apply any vendor-released patches or updates as soon as they become available; if no patch is currently available, consider temporary mitigations such as disabling or restricting access to the vulnerable component or isolating affected systems. 5. Conduct a thorough review of user privileges within the CMS to ensure least privilege principles are enforced, minimizing the number of users with high-level access. 6. Implement web application firewalls (WAFs) with custom rules to detect and block suspicious payloads targeting code injection or template manipulation. 7. Prepare incident response plans to quickly contain and remediate any exploitation attempts. 8. Engage with Redaxo community or vendor channels for updates and guidance on this vulnerability.
