CVE-2022-22965
Critical · 9.8
KEV Urgent · 83 Public exploit CWE-94 Apr 1, 2022
Spring Framework JDK 9+ Remote Code Execution Vulnerability
A Spring MVC or Spring WebFlux application running on JDK 9+ may be vulnerable to remote code execution (RCE) via data binding. The specific exploit requires the application to run on Tomcat as a WAR deployment. If the application is deployed as a Spring Boot executable jar, i.e. the default, it is not vulnerable to the exploit. However, the nature of the vulnerability is more general, and there may be other ways to exploit it.
CVE-2021-27878
High · 8.8
KEV Urgent · 78 Public exploit Ransomware Mar 1, 2021
Veritas Backup Exec Agent Command Execution Vulnerability
An issue was discovered in Veritas Backup Exec before 21.2. The communication between a client and an Agent requires successful authentication, which is typically completed over a secure TLS communication. However, due to a vulnerability in the SHA Authentication scheme, an attacker is able to gain unauthorized access and complete the authentication process. Subsequently, the client can execute data management protocol commands on the authenticated connection. The attacker could use one of these commands to execute an arbitrary command on the system using system privileges.
CVE-2021-27877
Critical · 9.8
KEV Urgent · 93 Public exploit Ransomware Mar 1, 2021
Veritas Backup Exec Agent Improper Authentication Vulnerability
An issue was discovered in Veritas Backup Exec before 21.2. It supports multiple authentication schemes: SHA authentication is one of these. This authentication scheme is no longer used in current versions of the product, but hadn't yet been disabled. An attacker could remotely exploit this scheme to gain unauthorized access to an Agent and execute privileged commands.
CVE-2021-27876
High · 8.1
KEV Urgent · 83 Public exploit Ransomware Mar 1, 2021
Veritas Backup Exec Agent File Access Vulnerability
An issue was discovered in Veritas Backup Exec before 21.2. The communication between a client and an Agent requires successful authentication, which is typically completed over a secure TLS communication. However, due to a vulnerability in the SHA Authentication scheme, an attacker is able to gain unauthorized access and complete the authentication process. Subsequently, the client can execute data management protocol commands on the authenticated connection. By using crafted input parameters in one of these commands, an attacker can access an arbitrary file on the system using System privileges.
