Patch a critical vulnerability in Locale::Maketext


This extensions applies a "hotfix" for Item12285 to your Foswiki 1.1.0 thru 1.1.6 system. Foswiki 1.0.x versions need to be manually patched.

ALERT! NOTICE: This patch addresses a critical Foswiki vulnerability and should be installed as soon as possible.

If a warning about MAKETEXT Rejected is displayed here, your system is patched: Excessive parameter number 101, MAKETEXT rejected.

When this extension is installed, it uses the Post-installation exit to apply any patch files found in the manifest. This extension ships with a hotfix for the following items:

Original Issue Patch File Description Applies to
Item12285 Item12285-001 Addresses a vulnerability in Locale::Maketext. Foswiki 1.1.0 - Foswiki 1.1.2
Item12285 Item12285-002 Addresses a vulnerability in Locale::Maketext. Foswiki 1.1.3 - Foswiki 1.1.6

Before any file is patched, a backup is copied to working/configure/backup/<Item12285-001-date-time>. Each file that is a candidate to be patched is backed up. If the extensions is installed multple times, a new backup is made for each run, regardless of whether or not the patch will be applied. For this patch, the following files are copied:
  • lib/Foswiki/Macros/MAKETEXT.pm

Patches are only applied if the target file is an exact match to the original file. There is no attempt to do "fuzzy" patching. Note however that a patch can be built to cover multiple versions of the file.

There is no "dependency order" established between patches. Patches are installed in order of their patch file name.

Patches will be mapped from the default Foswiki filename to the directory location used on the target system.

Note: This extension was re-released with a slightly different patch. It is strongly recommmended that prior versions of the patch be reverted and the final version be applied.


You do not need to install anything in the browser to use this extension. The following instructions are for the administrator who installs the extension on the server.
