N Able · N-Able Take Control Agent · CVE-2023-27470
**Name of the Vulnerable Software and Affected Versions**
N-able Take Control Agent versions 7.0.41.1141 through 7.0.42
**Description**
The issue is related to a Time-of-Check to Time-of-Use (TOCTOU) race condition in the BASupSrvcUpdater.exe service, which can be exploited via a pseudo-symlink at %PROGRAMDATA%GetSupportService N-CentralPushUpdates. This can lead to arbitrary file deletion. The vulnerability may allow an attacker to gain access to read, modify, or delete files.
**Recommendations**
For versions 7.0.41.1141 through 7.0.42, update to version 7.0.43 or later to resolve the issue.
As a temporary workaround, consider restricting access to the %PROGRAMDATA%GetSupportService N-CentralPushUpdates directory to minimize the risk of exploitation.
