CVE-2024-11053
Public on
Last Modified:
Description
A flaw was found in curl. A logic error when processing credentials from the .netrc file while performing redirects allows the transfer of credentials from the original host to the followed-to host under certain circumstances, leaking the credentials to the followed-to host.
Statement
This issue only affects curl when a .netrc
file is used and a redirect is performed. Additionally, the .netrc
must match the target hostname but the followed-to host does not have a password or both login and password configured.
Example of a vulnerable .netrc configuration:
machine a.com
login alice
password alicespassword
default
login bob
Mitigation
Avoid using the .netrc file together with redirects.

Common Vulnerability Scoring System (CVSS) Score Details
Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
Red Hat | NVD | |
---|---|---|
CVSS v3 Base Score | 5.9 | N/A |
Attack Vector | Network | N/A |
Attack Complexity | High | N/A |
Privileges Required | None | N/A |
User Interaction | None | N/A |
Scope | Unchanged | N/A |
Confidentiality Impact | High | N/A |
Integrity Impact | None | N/A |
Availability Impact | None | N/A |
