The optional ShellUserGroupProvider in Apache NiFi 1.10.0 to 1.16.2 and Apache NiFi Registry 0.6.0 to 1.16.2 does not neutralize arguments for group resolution commands, allowing injection of operating system commands on Linux and macOS platforms. The ShellUserGroupProvider is not included in the default configuration. Command injection requires ShellUserGroupProvider to be one of the enabled User Group Providers in the Authorizers configuration. Command injection also requires an authenticated user with elevated privileges. Apache NiFi requires an authenticated user with authorization to modify access policies in order to execute the command. Apache NiFi Registry requires an authenticated user with authorization to read user groups in order to execute the command. The resolution removes command formatting based on user-provided arguments.

A Server-Side Request Forgery (SSRF) vulnerability in IPS Community Suite before 4.6.2 allows remote authenticated users to request arbitrary URLs or trigger deserialization via phar protocol when generating class names dynamically. In some cases an exploitation is possible by an unauthenticated user.

x86 pv: Race condition in typeref acquisition Xen maintains a type reference count for pages, in addition to a regular reference count. This scheme is used to maintain invariants required for Xen's safety, e.g. PV guests may not have direct writeable access to pagetables; updates need auditing by Xen. Unfortunately, the logic for acquiring a type reference has a race condition, whereby a safely TLB flush is issued too early and creates a window where the guest can re-establish the read/write mapping before writeability is prohibited.

x86 pv: Insufficient care with non-coherent mappings T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Xen maintains a type reference count for pages, in addition to a regular reference count. This scheme is used to maintain invariants required for Xen's safety, e.g. PV guests may not have direct writeable access to pagetables; updates need auditing by Xen. Unfortunately, Xen's safety logic doesn't account for CPU-induced cache non-coherency; cases where the CPU can cause the content of the cache to be different to the content in main memory. In such cases, Xen's safety logic can incorrectly conclude that the contents of a page is safe.

Cross-site Scripting (XSS) - Reflected in GitHub repository neorazorx/facturascripts prior to 2022.1.

An issue was discovered in the IGEL Universal Management Suite (UMS) 6.07.100. A hardcoded DES key in the LDAPDesPWEncrypter class allows an attacker, who has discovered encrypted LDAP bind credentials, to decrypt those credentials using a static 8-byte DES key.

Backdoor.Win32.Cabrotor.10.d malware suffers from an unauthenticated remote command execution vulnerability.

Haron 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.

Trojan-Proxy.Win32.Symbab.o malware suffers from a heap corruption vulnerability.

Trojan-Banker.Win32.Banbra.cyt malware suffers from an insecure permissions vulnerability.
