OutSystems became aware of a vulnerability that, if exploited, may allow an attacker to compromise the availability, and integrity of the data handled and stored by the Platform Server.
OutSystems doesn't have any indication or reason to believe that this vulnerability has been exploited in the wild.
Only products listed at Vulnerable products and versions are known to be affected by this vulnerability. All other products aren’t affected by the aforementioned vulnerability.
Vulnerable products and versions
This vulnerability affects all versions of the Platform Server and LifeTime.
One of the OutSystems services contained a path traversal vulnerability that would allow a developer to write arbitrary files to a location where the files could be executed. Since services run with high privileges, this could potentially lead to fully compromising the host and gaining access to any file or key present on the filesystem.
There's no workaround, we strongly advise to update to the fixed versions.
Fixed products and versions
For OutSystems Cloud infrastructures, OutSystems notified all its cloud customers and applied a no-downtime hotfix targeted at the specific version of each customer. The hotfix didn't require an update of the Platform Server version.
For self-managed, you should upgrade to one of the following releases (or subsequent release);
- Platform Server: 10.0.1102.0 and 11.9.0
- LifeTime: 11.7.0
