Technical Analysis

CVE-2025-11853 identifies an improper access control vulnerability in the Sismics Teedy document management system, specifically affecting the /api/file endpoint across all versions up to 1.11. The vulnerability allows remote attackers to perform unauthorized manipulations on the API, potentially accessing or modifying files without proper authorization. The flaw arises from insufficient enforcement of access control checks within the API endpoint, which could be exploited without user interaction and with only limited privileges, indicating a design or implementation oversight. The vendor was notified early but has not issued any patches or advisories, and the exploit details have been publicly disclosed, raising the risk of active exploitation despite no known exploits in the wild currently. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P) indicates network attack vector, low attack complexity, no authentication required beyond limited privileges, no user interaction, and partial impact on confidentiality, integrity, and availability. This vulnerability could allow attackers to access sensitive documents, alter stored data, or disrupt document management workflows, undermining organizational security and compliance. Given Teedy's role in managing potentially sensitive corporate documents, exploitation could lead to data breaches or operational disruptions.

Potential Impact

For European organizations, the impact of CVE-2025-11853 can be significant, especially for those relying on Sismics Teedy for document management in regulated industries such as finance, healthcare, legal, and government sectors. Unauthorized access or manipulation of documents could lead to exposure of confidential information, violation of data protection regulations like GDPR, and loss of data integrity affecting business operations. The medium severity rating reflects a moderate but tangible risk, as attackers with limited privileges can exploit the vulnerability remotely without user interaction. This could facilitate lateral movement within networks or data exfiltration. The absence of vendor patches increases the window of exposure, potentially attracting threat actors to target European entities using Teedy. Additionally, disruption of document workflows could impact productivity and trust in digital document management solutions.

Mitigation Recommendations

To mitigate CVE-2025-11853, European organizations should immediately implement strict network-level access controls to limit exposure of the /api/file endpoint to trusted internal networks or VPNs. Employ API gateways or web application firewalls (WAFs) to enforce additional access control policies and monitor for anomalous API requests indicative of exploitation attempts. Conduct thorough audits of user privileges within Teedy to ensure minimal necessary access is granted, reducing the risk posed by compromised accounts with limited privileges. Enable detailed logging and continuous monitoring of API activity to detect suspicious behavior early. Organizations should also consider isolating Teedy instances in segmented network zones to contain potential breaches. Until an official patch is released, avoid exposing Teedy APIs directly to the internet. Engage with the vendor or community for updates and apply patches promptly once available. Finally, educate internal teams about this vulnerability and incorporate it into incident response plans.
