In order to ensure full traceability, we need a CVE number assigned that we can attach to further notifications. This issue is already public. Title: Incomplete fix to CVE-2015-3297 in Etherpad Minify Reporter: anonymous Versions: 1.1.2 through 1.5.4 Description: An anonymous reporter pointed out an incomplete fix to CVE-2015-3297 in the minify feature of current Etherpad releases. There is an additional location in the script where backslashes are replaced with slashes in the path parameter of HTTP API calls after path normalization is applied, allowing an attacker supplying a slightly different specially-crafted request to remotely read arbitrary files on the server's filesystem with the privileges of the account running the service. Notes: This bug was introduced in commit a97b83b which was initially included in the 1.1.2 release (a later commit than the one which introduced CVE-2015-3297 in 1.1.1), and is fixed in commit 0fa7650 which will appear in a future 1.5.5 release.
