Welcome to our detailed guide on CVE-2024-11053, which emerged as a concerning issue for users of the widely utilized curl command-line tool. This article is tailored to help LinuxPatch customers comprehend the implications of this low-severity vulnerability and how it could potentially impact your system's security.
CVE-2024-11053 Basics
Identified as CVE-2024-11053, this security flaw was given a severity rating of LOW, with a CVSS (Common Vulnerability Scoring System) score of 3.4. It specifically targets the operation of the curl tool under certain conditions involving HTTP redirects and the usage of a .netrc file for credentials.
What is Curl?
Curl is an essential software tool used on a variety of operating systems to transfer data from or to a server. It supports various protocols, including HTTP, HTTPS, FTP, and more. One common use of curl is in scripts or automation tasks where web content needs to be downloaded or API calls need to be executed programmatically. This makes curl an indispensable tool in many developers' and system administrators' toolkits.
The Issue at Hand
The vulnerability arises when curl is instructed to use a .netrc file for managing server credentials in combination with following HTTP redirects. Under such conditions, the password used for the initial host can unintentionally be sent to the redirected host. However, this only occurs if the .netrc file has an entry that matches the redirect target's hostname but lacks complete credentials (either omitting the password or both the login and password).
Impact on Users
This flaw, given its specific conditionality, is less likely to be encountered by most users. Nonetheless, in environments where .netrc files are commonly used and external redirects are processed, there could be an unwanted exposure of credentials. This highlights a narrow but noteworthy risk in certain automated or scripted curl transactions.
