Sophos: Security Vulnerabilities
An exploitable double fetch vulnerability exists in the SboxDrv.sys driver functionality of Invincea-X 6.1.3-24058. A specially crafted input buffer and race condition can result in kernel memory corruption, which could result in privilege escalation. An attacker needs to execute a special application locally to trigger this vulnerability.

Sophos Endpoint Protection 10.7 uses an unsalted SHA-1 hash for password storage in %PROGRAMDATA%\Sophos\Sophos Anti-Virus\Config\machine.xml, which makes it easier for attackers to determine a cleartext password, and subsequently choose unsafe malware settings, via rainbow tables or other approaches.

In Sophos Tester Tool 3.2.0.7 Beta, the driver loads (in the context of the application used to test an exploit or ransomware) the DLL using a payload that runs from NTDLL.DLL (so, it's run in userland), but the driver doesn't perform any validation of this DLL (not its signature, not its hash, etc.). A person can change this DLL in a local way, or with a remote connection, to a malicious DLL with the same name -- and when the product is used, this malicious DLL will be loaded, aka a DLL Hijacking attack.

In Sophos Tester Tool 3.2.0.7 Beta, the driver accepts a special DeviceIoControl code that doesn't check its argument. This argument is a memory address: if a caller passes a NULL pointer or a random invalid address, the driver will cause a Blue Screen of Death. If a program or malware does this at boot time, it can cause a persistent denial of service on the machine.

An NC-25986 issue was discovered in the Logging subsystem of Sophos XG Firewall with SFOS before 17.0.3 MR3. An unauthenticated user can trigger a persistent XSS vulnerability found in the WAF log page (Control Center -> Log Viewer -> in the filter option "Web Server Protection") in the webadmin interface, and execute any action available to the webadmin of the firewall (e.g., creating a new user, enabling SSH, or adding an SSH authorized key). The WAF log page will execute the "User-Agent" parameter in the HTTP POST request.
