How to Fix CVE-2020-35136

To remediate this vulnerability, upgrade all affected Dolibarr/dolibarr dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

dolibarr/dolibarr fixed: 12.0.4 
Upgrade dolibarr/dolibarr to 12.0.4
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for dolibarr/dolibarr

How to Check if You Are Affected

To determine whether your application is affected by CVE-2020-35136, inspect your project dependencies for Dolibarr/dolibarr:

inspect dependencies for dolibarr/dolibarr

Analyze the terminal output to locate any version of Dolibarr/dolibarr in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 12.0.4), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection'), where the product constructs a string for a command to be executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string. In Dolibarr/dolibarr, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Dolibarr 12.0.3 is vulnerable to authenticated Remote Code Execution. An attacker who has the access the admin dashboard can manipulate the backup function by inserting a payload into the filename for the zipfilename_template parameter to admin/tools/dolibarr_export.php.
