SolarWinds fixed three critical RCE flaws in its Access Rights Manager product

Researchers discovered three critical remote code execution vulnerabilities in the SolarWinds Access Rights Manager (ARM) product.

Security researchers discovered three critical remote code execution vulnerabilities in the SolarWinds Access Rights Manager (ARM) product.

SolarWinds Access Rights Manager (ARM) is a software solution developed by IT management and monitoring software provider SolarWinds, it was designed to help organizations manage and monitor user access and permissions in their IT environments.

The three flaws were reported on June 22 along with other five issues through Trend Micro’s Zero Day Initiative (ZDI).

The three critical RCE flaws are:

• CVE-2023-35182 (9.8 severity): This vulnerability allows remote attackers to execute arbitrary code on affected installations of SolarWinds Access Rights Manager. Authentication is not required to exploit this vulnerability. The specific flaw exists within the createGlobalServerChannelInternal method. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of SYSTEM.
• CVE-2023-35185 (9.8 severity): This vulnerability allows remote attackers to execute arbitrary code on affected installations of SolarWinds Access Rights Manager. Authentication is not required to exploit this vulnerability. The specific flaw exists within the OpenFile method. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code in the context of SYSTEM.
• CVE-2023-35187 (9.8 severity): This vulnerability allows remote attackers to execute arbitrary code on affected installations of SolarWinds Access Rights Manager. Authentication is not required to exploit this vulnerability.The specific flaw exists within the OpenClientUpdateFile method. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to execute code in the context of SYSTEM.

SolarWinds addressed these flaws on October 18, with the release of ACM version 2023.2.1.
