DESCRIPTION

The 1E-Exchange-DisplayMessageinstruction that is part of the End-User Interaction product pack available on the 1E Exchange does not properly validate the Caption or Message parameters, which allows for a specially crafted input to perform arbitrary code execution with SYSTEM permissions.

To remediate this issue DELETE the instruction “Show dialogue with caption %Caption% and message %Message%” from the list of instructions in the Settings UI, and replace it with the new instruction 1E-Exchange-ShowNotification instruction available in the updated End-User Interaction product pack. The new instruction should show as “Show %Type% type notification with header %Header% and message %Message%” with a version of 7.1 or above.

https://www.1e.com/trust-security-compliance/cve-info/

DESCRIPTION

1E Client installer can perform arbitrary file deletion on protected files. A non-privileged user could provide a symbolic link or Windows junction to point to a protected directory in the installer that the 1E Client would then clear on service startup.

A hotfix is available from the 1E support portal that forces the 1E Client to check for a symbolic link or junction and if it finds one refuses to use that path and instead creates a path involving a random GUID.

for v8.1 use hotfix Q23097
for v8.4 use hotfix Q23105
for v9.0 use hotfix Q23115

for SaaS customers, use 1EClient v23.7 plus hotfix Q23121

DESCRIPTION

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.

DESCRIPTION

The %PROGRAMDATA%\1E\Client directory in 1E Client 5.0.0.745 and 4.1.0.267 allows remote authenticated users and local users to create and modify files in protected directories (where they would not normally have access to create or modify files) via the creation of a junction point to a system directory. This leads to partial privilege escalation. This vulnerability can be mitigated by changing the permission of the ProgramData\1E\Client directory so that a standard user does not have the ability to create and modify files.
