RegreSSHion is a family of security bugs in the OpenSSH software that allows for an attacker to remotely execute code and gain potential root access on a machine running the OpenSSH Server. [1] [2] The vulnerability was discovered by the Qualys Threat Research Unit and was disclosed on July 1, 2024.
The malicious code is known to be in 5.6.0 and 5.6.1 releases of the XZ Utils software package. The exploit remains dormant unless a specific third-party patch of the SSH server is used. Under the right circumstances this interference could potentially enable a malicious actor to break sshd authentication and gain unauthorized access to the ...
CopSSH is an implementation of OpenSSH for Windows. CopSSH offers both SSH client and server functionality and can be used for remote administration of Windows systems. CopSSH contains DLLs from the Cygwin Linux environment and a version of OpenSSH compiled from C
On its own, an arbitrary code execution exploit will give the attacker the same privileges as the target process that is vulnerable. [11] For example, if exploiting a flaw in a web browser, an attacker could act as the user, performing actions such as modifying personal computer files or accessing banking information, but would not be able to perform system-level actions (unless the user in ...
OpenSSH is not a single computer program, but rather a suite of programs that serve as alternatives to unencrypted protocols like Telnet and FTP. OpenSSH is integrated into several operating systems, namely Microsoft Windows, macOS and most Linux operating systems, [7] [8] while the portable version is available as a package in other systems ...
The researchers who discovered the attack have also created a vulnerability scanner to determine whether an SSH server or client is vulnerable. [8] The attack has been given the CVE ID CVE-2023-48795. [9] [3] In addition to the main attack, two other vulnerabilities were found in AsyncSSH, and assigned the CVE IDs CVE-2023-46445 and CVE-2023 ...
PrintNightmare is a critical security vulnerability affecting the Microsoft Windows operating system. [2] [5] The vulnerability occurred within the print spooler service. [6] [7] There were two variants, one permitting remote code execution (CVE-2021-34527), and the other leading to privilege escalation (CVE-2021-1675).
The vulnerabilities are a mixture of information leak vulnerabilities, remote code execution vulnerability or logical flaw vulnerabilities. The Apple iOS vulnerability was a remote code execution vulnerability due to the implementation of LEAP (Low Energy Audio Protocol). This vulnerability was only present in older versions of the Apple iOS. [17]
