Veeam Backup & Replication Credential Exposure Vulnerability
CVE-2024-42451 6.5 - Medium - December 04, 2024

A vulnerability in Veeam Backup & Replication allows low-privileged users to leak all saved credentials in plaintext. This is achieved by calling a series of methods over an external protocol, ultimately retrieving the credentials using a malicious setup on the attacker's side. This exposes sensitive data, which could be used for further attacks, including unauthorized access to systems managed by the platform.

Veeam Backup & Replication Remote Code Execution via Job Update
CVE-2024-40717 8.8 - High - December 04, 2024

A vulnerability in Veeam Backup & Replication allows a low-privileged user with certain roles to perform remote code execution (RCE) by updating existing jobs. These jobs can be configured to run pre- and post-scripts, which can be located on a network share and are executed with elevated privileges by default. The user can update a job and schedule it to run almost immediately, allowing arbitrary code execution on the server.

Veeam Backup & Replication Remote Agent Privilege Escalation Vulnerability
CVE-2024-42452 8.8 - High - December 04, 2024

A vulnerability in Veeam Backup & Replication allows a low-privileged user to start an agent remotely in server mode and obtain credentials, effectively escalating privileges to system-level access. This allows the attacker to upload files to the server with elevated privileges. The vulnerability exists because remote calls bypass permission checks, leading to full system compromise.

Veeam Backup & Replication: Improper Permission Checks in Management Services
CVE-2024-42453 8.1 - High - December 04, 2024

A vulnerability Veeam Backup & Replication allows low-privileged users to control and modify configurations on connected virtual infrastructure hosts. This includes the ability to power off virtual machines, delete files in storage, and make configuration changes, potentially leading to Denial of Service (DoS) and data integrity issues. The vulnerability is caused by improper permission checks in methods accessed via management services.

Veeam Backup & Replication Insecure Deserialization Vulnerability
CVE-2024-42455 8.1 - High - December 04, 2024

A vulnerability in Veeam Backup & Replication allows a low-privileged user to connect to remoting services and exploit insecure deserialization by sending a serialized temporary file collection. This exploit allows the attacker to delete any file on the system with service account privileges. The vulnerability is caused by an insufficient blacklist during the deserialization process.

Veeam Backup & Replication: Insufficient Permission Control in Configuration Update Method
CVE-2024-42456 8.8 - High - December 04, 2024

A vulnerability in Veeam Backup & Replication platform allows a low-privileged user with a specific role to exploit a method that updates critical configuration settings, such as modifying the trusted client certificate used for authentication on a specific port. This can result in unauthorized access, enabling the user to call privileged methods and initiate critical services. The issue arises due to insufficient permission requirements on the method, allowing users with low privileges to perform actions that should require higher-level permissions.

Windows Credential Manager NTLM Hash Leak Vulnerability
CVE-2024-45204 4.3 - Medium - December 04, 2024

A vulnerability exists where a low-privileged user can exploit insufficient permissions in credential handling to leak NTLM hashes of saved credentials. The exploitation involves using retrieved credentials to expose sensitive NTLM hashes, impacting systems beyond the initial target and potentially leading to broader security vulnerabilities.

Veeam Backup & Replication: Remote Management Interface Credential Exposure Vulnerability
CVE-2024-42457 6.5 - Medium - December 04, 2024

A vulnerability in Veeam Backup & Replication allows users with certain operator roles to expose saved credentials by leveraging a combination of methods in a remote management interface. This can be achieved using a session object that allows for credential enumeration and exploitation, leading to the leak of plaintext credentials to a malicious host. The attack is facilitated by improper usage of a method that allows operators to add a new host with an attacker-controlled IP, enabling them to retrieve sensitive credentials in plaintext.

Veeam Backup & Replication MITM Auth Bypass
CVE-2024-40715 - November 07, 2024

A vulnerability in Veeam Backup & Replication Enterprise Manager has been identified, which allows attackers to perform authentication bypass. Attackers must be able to perform Man-in-the-Middle (MITM) attack to exploit this vulnerability.

Path Traversal LPE via Local Low-Privileged Account (CVE-2024-40712)
CVE-2024-40712 7.8 - High - September 07, 2024

A path traversal vulnerability allows an attacker with a low-privileged account and local access to the system to perform local privilege escalation (LPE).

IIV permits low-privileged user to delete files as service acc.
CVE-2024-39718 8.1 - High - September 07, 2024

An improper input validation vulnerability that allows a low-privileged user to remotely remove files on the system with permissions equivalent to those of the service account.

Veeam Backup & Replication RCE via lowprivileged role
CVE-2024-40710 8.8 - High - September 07, 2024

A series of related high-severity vulnerabilities, the most notable enabling remote code execution (RCE) as the service account and extraction of sensitive information (savedcredentials and passwords). Exploiting these vulnerabilities requires a user who has been assigned a low-privileged role within Veeam Backup & Replication.

Privilege Escalation via MFA Disable in Veeam Backup & Replication
CVE-2024-40713 7.8 - High - September 07, 2024

A vulnerability that allows a user who has been assigned a low-privileged role within Veeam Backup & Replication to alter Multi-Factor Authentication (MFA) settings and bypass MFA.
