Argument injection through Mercurial repository uri handling on Windows - CVE-2018-5223

XMLWordPrintable

      Fisheye and Crucible did not correctly check if a configured Mercurial repository URI contained values that the Windows operating system may consider argument parameters. An attacker who has permission to add a repository in Fisheye or Crucible can execute code of their choice on systems that run a vulnerable version of Fisheye or Crucible on the Windows operating system.

      Affected versions:

      • All versions of Fisheye and Crucible before 4.4.6 (the fixed version for 4.4.x) and from 4.5.0 before 4.5.3 (the fixed version for 4.5.x) are affected by this vulnerability.

      Fix:
