This weekly blog post is from via our unique intelligence collection pipelines. We are your eyes and ears online, including the Dark Web.
There are thousands of vulnerability discussions each week. SOS Intelligence gathers a list of the most discussed Common Vulnerabilities and Exposures (CVE) online for the previous week.
We make every effort to ensure the accuracy of the data presented. As this is an automated process some errors may creep in.
If you are feeling generous please do make us aware of anything you spot, feel free to follow us on Twitter @sosintel and DM us. Thank you!
1. CVE-2025-20352
A vulnerability in the VPN web server of Cisco Secure Firewall Adaptive Security Appliance (ASA) Software and Cisco Secure Firewall Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to access restricted URL endpoints that are related to remote access VPN that should otherwise be inaccessible without authentication.
This vulnerability is due to improper validation of user-supplied input in HTTP(S) requests. An attacker could exploit this vulnerability by sending crafted HTTP requests to a targeted web server on a device. A successful exploit could allow the attacker to access a restricted URL without authentication.

3. CVE-2025-20333
A vulnerability in the VPN web server of Cisco Secure Firewall Adaptive Security Appliance (ASA) Software and Cisco Secure Firewall Threat Defense (FTD) Software could allow an authenticated, remote attacker to execute arbitrary code on an affected device.
This vulnerability is due to improper validation of user-supplied input in HTTP(S) requests. An attacker with valid VPN user credentials could exploit this vulnerability by sending crafted HTTP requests to an affected device. A successful exploit could allow the attacker to execute arbitrary code as root, possibly resulting in the complete compromise of the affected device.
