CVE-2025-67079 is a critical file upload vulnerability affecting Omnispace Agora Project versions prior to 25.10. The vulnerability arises from improper handling of uploaded PDF files processed by the MSL engine within the Imagick library, which is used for image manipulation and thumbnail generation. Attackers can craft malicious PDF files that, when uploaded, trigger code execution within the context of the application server. This occurs because the MSL engine processes embedded content in the PDF, allowing exploitation of the underlying Imagick library's parsing flaws. The vulnerability does not require prior authentication or user interaction, making it highly exploitable remotely. The lack of a CVSS score indicates this is a newly disclosed issue, but the potential for remote code execution and system compromise is significant. No patches or known exploits are currently reported, but the risk remains high for organizations using affected versions. The vulnerability impacts confidentiality, integrity, and availability by enabling attackers to execute arbitrary code, potentially leading to data breaches, system takeover, or denial of service. The threat is particularly relevant for environments where Omnispace Agora Project is used to handle user-uploaded files, such as content management systems, collaboration platforms, or cloud services.

For European organizations, this vulnerability poses a serious risk, especially those relying on Omnispace Agora Project for file upload and processing functionalities. Successful exploitation could lead to unauthorized remote code execution, allowing attackers to gain control over affected servers, exfiltrate sensitive data, disrupt services, or pivot within internal networks. Critical sectors such as finance, healthcare, government, and telecommunications could face severe operational and reputational damage. The ability to execute code without authentication increases the attack surface, making automated attacks feasible. Additionally, the processing of PDF files is common in many workflows, increasing the likelihood of exploitation. The absence of known exploits currently provides a window for proactive mitigation, but the potential impact on confidentiality, integrity, and availability is substantial. European organizations with regulatory obligations under GDPR must also consider the compliance risks associated with data breaches stemming from this vulnerability.

Immediate mitigation should focus on restricting file upload capabilities to trusted users and implementing strict validation of uploaded files, including file type, size, and content inspection. Employ sandboxing or containerization for file processing tasks to isolate the Imagick library execution environment. Monitor logs for unusual file upload activity or errors related to PDF processing. Network segmentation can limit the impact of a compromised server. Since no official patches are currently available, organizations should engage with Omnispace support for timelines and consider temporary disabling of thumbnail generation or PDF processing features if feasible. Employ Web Application Firewalls (WAFs) with custom rules to detect and block malicious PDF payloads targeting the MSL engine. Regularly update and audit all dependencies, including Imagick, to ensure known vulnerabilities are addressed. Prepare incident response plans specific to remote code execution scenarios and conduct employee awareness training on secure file handling practices.
