Microsoft is warning of a new variant of the srv botnet that's exploiting multiple security flaws in web applications and databases to install coin miners on both Windows and Linux systems. The tech giant, which has called the new version Sysrv-K, is said to weaponize an array of exploits to gain control of web servers. The cryptojacking botnet first emerged in December 2020. "Sysrv-K scans the

Local privilege escalation due to excessive permissions assigned to child processes. The following products are affected: Acronis Snap Deploy (Windows) before build 3640

Local privilege escalation due to a DLL hijacking vulnerability. The following products are affected: Acronis Snap Deploy (Windows) before build 3640

Local privilege escalation due to insecure folder permissions. The following products are affected: Acronis Snap Deploy (Windows) before build 3640

Prime95 30.7 build 9 suffers from a Buffer Overflow vulnerability that could lead to Remote Code Execution.

Trend Micro Password Manager (Consumer) version 5.0.0.1266 and below is vulnerable to a Link Following Privilege Escalation Vulnerability that could allow a low privileged local attacker to delete the contents of an arbitrary folder as SYSTEM which can then be used for privilege escalation on the affected machine.

Parallels H-Sphere 3.6.1713 allows XSS via the index_en.php from parameter.

IpMatcher versions 1.0.4.1 and below for .NET Core 2.0 and .NET Framework 4.5.2 incorrectly validates octal and hexadecimal input data which can lead to indeterminate server-side request forgery, local file inclusion, remote file inclusion, and denial of service vectors.

Conti ransomware looks for and executes DLLs in its current directory. Therefore, we can potentially hijack a DLL to execute our own code and control and terminate the malware pre-encryption. The exploit dll will check if the current directory is "C:\Windows\System32" and if not we grab our process ID and terminate. We do not need to rely on hash signatures or third-party products as the malware's own flaw will do the work for us. Endpoint protection systems and or antivirus can potentially be killed prior to executing malware, but this method cannot as there's nothing to kill the DLL that just lives on disk waiting. From a defensive perspective you can add the DLLs to a specific network share containing important data as a layered approach. All basic tests were conducted successfully in a virtual machine environment.
