Vulnerabilities

Improper link resolution before file access in the Nomad module of the 1E Client, in versions prior to 25.3, enables an attacker with local unprivileged access on a Windows system to delete arbitrary files on the device by exploiting symbolic links.

The 1E Platform's component utilized the third-party Duende Identity Server, which suffered from an open redirect vulnerability, permitting an attacker to control the redirection path of end users. Note: 1E Platform's component utilizing the third-party Duende Identity Server has been updated with the patch that includes the fix.

The 1E-Exchange-CommandLinePing instruction that is part of the Network product pack available on the 1E Exchange does not properly validate the input parameter, which allows for a specially crafted input to perform arbitrary code execution with SYSTEM permissions. This instruction only runs on Windows clients. To remediate this issue download the updated Network product pack from the 1E Exchange and update the 1E-Exchange-CommandLinePing instruction to v18.1 by uploading it through the 1E Platform instruction upload UI

Affected 1E Platform versions have a Blind SQL Injection vulnerability that can lead to arbitrary code execution. Application of the relevant hotfix remediates this issue. for v8.1.2 apply hotfix Q23166 for v8.4.1 apply hotfix Q23164 for v9.0.1 apply hotfix Q23169 SaaS implementations on v23.7.1 will automatically have hotfix Q23173 applied. Customers with SaaS versions below this are urged to upgrade urgently - please contact 1E to arrange this

In the affected version of the 1E Client, an ordinary user could subvert downloaded instruction resource files, e.g., to substitute a harmful script. by replacing a resource script file created by an instruction at run time with a malicious script. The 1E Client's temporary directory is now locked down in the released patch. Resolution: This has been fixed in patch Q23094 This issue has also been fixed in the Mac Client in updated versions of Non-Windows release v8.1.2.62 - please re-download from the 1E Support site. Customers with Mac Client versions higher than v8.1 will need to upgrade to v23.11 to remediate this vulnerability.

The MSI installer in 1E Client 4.1.0.267 and 5.0.0.745 allows remote authenticated users and local users to gain elevated privileges via the repair option. This applies to installations that have a TRANSFORM (MST) with the option to disable the installation of the Nomad module. An attacker may craft a .reg file in a specific location that will be able to write to any registry key as an elevated user.
