CVE-2018-25091
CVSS v2.0
6.4
Medium
| Vector | AV:N/AC:L/Au:N/C:P/I:P/A:N |
Name of the Vulnerable Software and Affected Versions
urllib3 versions prior to 1.24.2
Description
The issue is related to the use of open redirects in the Urllib3 HTTP library for Python. Exploitation of this issue can allow a remote attacker to access and compromise confidential data. Specifically, when following a cross-origin redirect, the library does not remove the authorization HTTP header, potentially exposing credentials to unintended hosts or transmitting them in cleartext.
Recommendations
For versions prior to 1.24.2, update to version 1.24.2 or later to resolve the issue. As a temporary workaround, consider disabling the use of cross-origin redirects until a patch is available. Restrict access to sensitive data and credentials to minimize the risk of exploitation.
Fix
Open Redirect
