CVE-2023-28322
Plain English Summary
AI-powered analysis for quick understanding
This vulnerability allows an attacker to potentially send incorrect data during an HTTP POST request if the same connection handle was previously used for a PUT request, which could lead to unexpected application behavior. It mainly affects applications that reuse connection handles without properly resetting them, making it important for developers to be cautious when switching between different types of requests.
Technical Description
An information disclosure vulnerability exists in curl <v8.1.0 when doing HTTP(S) transfers, libcurl might erroneously use the read callback (`CURLOPT_READFUNCTION`) to ask for data to send, even when the `CURLOPT_POSTFIELDS` option has been set, if the same handle previously wasused to issue a `PUT` request which used that callback. This flaw may surprise the application and cause it to misbehave and either send off the wrong data or use memory after free or similar in the second transfer. The problem exists in the logic for a reused handle when it is (expected to be) changed from a PUT to a POST.

Related Vulnerabilities
This vulnerability allows an attacker to potentially execute arbitrary code on a system using curl when making a second SMB request to the same host, due to the software mistakenly using memory that has already been freed. To exploit this, the attacker must be able to send multiple SMB requests to the same server, which could happen in certain network configurations.
This vulnerability allows an attacker to potentially gain access to sensitive information by reusing an existing HTTP proxy connection, even if the new request uses different login credentials. This issue occurs when the curl tool fails to establish a separate connection for requests that require different authentication, which could lead to unauthorized data exposure if an attacker can control the proxy or its traffic.
This vulnerability allows an attacker to potentially capture an OAuth2 bearer token when a user is redirected from one website to another, exposing sensitive information. This can happen if the second website has credentials stored in the user's .netrc file, which curl mistakenly sends along with the token.
This vulnerability allows an attacker to potentially access sensitive information by reusing an existing connection that was authenticated with different user credentials, leading to unauthorized actions. This can happen if an application makes multiple requests to the same server using Negotiate authentication, where the first request is authenticated with one user's credentials and the second request mistakenly uses that same connection, thinking it's authenticated with a different user's credentials.
An attacker can exploit a vulnerability in curl to send malicious commands during TELNET communication, potentially allowing them to execute arbitrary code on the system. This can happen if an application using curl accepts user input without properly checking it, making it particularly risky for applications that rely on user-provided data.
