# rcube_image.php in Roundcube Webmail before 1.4.4 allows attackers to execute arbitrary code via shell…

Roundcube Webmail, a web mail client, has a remote code execution flaw: shell metacharacters in the im_convert_path or im_identify_path configuration setting are passed to a shell. An attacker who can set those values can run arbitrary commands on the server.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- vendor:Roundcube Roundcube Webmail affected ? fixed ?
- vendor:roundcube webmail affected >= 1.2.0, < 1.2.10 fixed 1.2.10
- vendor:roundcube webmail affected >= 1.3.0, < 1.3.11 fixed 1.3.11
- vendor:roundcube webmail affected >= 1.4.0, < 1.4.4 fixed 1.4.4
- vendor:opensuse backports sle affected = 15.0 fixed ?
- vendor:opensuse leap affected = 15.1 fixed ?
- vendor:opensuse leap affected = 15.2 fixed ?

## How to check

Look at the Roundcube config file (config/config.inc.php) for im_convert_path and im_identify_path; unknown whether the sources give a version check.

## Fix

Update Roundcube Webmail to a fixed release per vendor instructions (CISA KEV required action); exact fixed version unknown from the sources.

## From the sources

Roundcube Webmail contains an remote code execution vulnerability that allows attackers to execute code via shell metacharacters in a configuration setting for im_convert_path or im_identify_path.

CISA required action: Apply updates per vendor instructions.
