Hi, I'm Sharon, a product manager at Chaitin Tech. We build SafeLine, an open-source Web Application Firewall built for real-world threats. While SafeLine focuses on HTTP-layer protection, our emergency response center monitors and responds to RCE and authentication vulnerabilities across the stack to help developers stay safe.
Seeyon OA is a widely used enterprise Office Automation (OA) platform that helps organizations streamline daily tasks and workflow management.
Recently, Seeyon released a new patch addressing a critical front-end vulnerability that allows attackers to reset any user’s password without authentication.
Chaitin Tech’s emergency response team analyzed the issue and confirmed that many internet-facing Seeyon OA systems remain unpatched and exploitable. To help defenders, they have released a harmless X-POC remote scanner and a CloudWalker local detection tool that are publicly available.
Vulnerability Description
A password reset API in Seeyon OA can be accessed without authentication.
By sending a crafted request, attackers can change the password of any user account — including privileged admin accounts.
This gives attackers a direct path to hijack corporate OA systems.

Great post, Sharon! Your detailed breakdown of the Seeyon OA password reset vulnerability is invaluable for anyone managing enterprise systems. It's alarming to see how easily attackers can exploit this flaw to hijack user accounts, including admin privileges.
The inclusion of detection tools like X-POC and CloudWalker is particularly helpful. It's crucial that organizations not only apply the official patch but also utilize these tools to assess their current security posture. The proactive steps you've outlined, such as restricting access via network ACLs and implementing virtual patches through SafeLine WAF, are essential for mitigating potential risks.
Your commitment to providing timely and actionable security insights is commendable. This post serves as a critical reminder of the importance of staying vigilant and responsive to emerging vulnerabilities.
Looking forward to more of your expert analyses and recommendations!
Thanks for sharing this alert! For anyone needing more detailed insights on popular café offerings, I recently found a helpful resource covering Dutch Bros menu guide that breaks down options, prices, and new items it might help teams stay informed while managing updates securely.
That’s an important security update thanks for sharing. Cyber threats can easily go unnoticed, so staying ahead with timely patches is critical. For anyone interested in keeping track of public records alongside security awareness, checking reliable sources like arrestsssss.org can provide additional insights. It’s always better to combine system protection with informed monitoring.
The Seeyon OA vulnerability is definitely a reminder of how quickly exploits can escalate if patches aren’t applied in time. It’s interesting to see how security issues like this connect with other sectors, including legal research tools. I recently came across Texas Criminal Data which provides structured insights that help in tracking sensitive information efficiently. Staying updated across fields seems more important than ever.
