How to Fix CVE-2013-1939

To remediate this vulnerability, upgrade all affected Sabre/dav dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

sabre/dav fixed: 1.7.7 
Upgrade sabre/dav to 1.7.7
sabre/dav fixed: 1.8.5 
Upgrade sabre/dav to 1.8.5
sabre/dav fixed: 1.6.9 
Upgrade sabre/dav to 1.6.9
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for sabre/dav

How to Check if You Are Affected

To determine whether your application is affected by CVE-2013-1939, inspect your project dependencies for Sabre/dav:

inspect dependencies for sabre/dav

Analyze the terminal output to locate any version of Sabre/dav in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.7.7), your application is affected.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Sabre/dav, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The HTML\Browser plugin in SabreDAV before 1.6.9, 1.7.x before 1.7.7, and 1.8.x before 1.8.5, as used in ownCloud, when running on Windows, does not properly check path separators in the base path, which allows remote attackers to read arbitrary files via a `\` (backslash) character.
