CVE-2021-21068 is a vulnerability in Adobe Creative Cloud Desktop Application
Published on March 12, 2021
Adobe Creative Cloud installer arbitrary file overwrite vulnerability
Adobe Creative Cloud Desktop Application version 5.3 (and earlier) is affected by a file handling vulnerability that could allow an attacker to cause arbitrary file overwriting. Exploitation of this issue requires physical access and user interaction.
Weakness Type
Creation of Temporary File in Directory with Insecure Permissions
The software creates a temporary file in a directory whose permissions allow unintended actors to determine the file's existence or otherwise access that file. On some operating systems, the fact that the temporary file exists may be apparent to any user with sufficient privileges to access that directory. Since the file is visible, the application that is using the temporary file could be known. If one has access to list the processes on the system, the attacker has gained information about what the user is doing at that time. By correlating this with the applications the user is running, an attacker could potentially discover what a user's actions are. From this, higher levels of security could be breached.
