VUL-0: CVE-2023-28322: curl: POST-after-PUT confusion
Last modified: 2024-04-15 15:07:52 UTC
CVE-2023-28322: more POST-after-PUT confusion ============================================= Project curl Security Advisory, May 17 2023 - [Permalink](https://curl.se/docs/CVE-2023-28322.html) VULNERABILITY ------------- 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 was used 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. INFO ---- The code actually sending wrong data or doing a use-after-free is not present in libcurl code but are only presumed scenarios that might become the outcome of libcurl surprisingly calling the read callback in a situation where it is not expected to. This flaw cannot be triggered with the command line tool. This problem is almost identical to [CVE-2022-32221](https://curl.se/docs/CVE-2022-32221.html). A difference this time is that setting `CURLOPT_POST` for the second transfer avoids the problem, where as only setting `CURLOPT_POSTFIELDS` after the PUT still makes the second transfer to a PUT and use the callback. The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2023-28322 to this issue. CWE-440: Expected Behavior Violation Severity: Low AFFECTED VERSIONS ----------------- - Affected versions: libcurl 7.7 to and including 8.0.1 - Not affected versions: libcurl < 7.7 and >= 8.1.0 - Introduced-in: https://github.com/curl/curl/commit/546572da0457f3 libcurl is used by many applications, but not always advertised as such! SOLUTION ------------ This time the logic is improved to avoid having two separate variable fields holding info about HTTP method and behavior. Now there is only one, which should make it harder to end up in such a confused middle state. - Fixed-in: https://github.com/curl/curl/commit/7815647d6582c0a4900be2e1de RECOMMENDATIONS -------------- A - Upgrade curl to version 8.1.0 B - Apply the patch to your local version C - Do not do mix using the read callback and postfields string on a reused easy handle TIMELINE -------- This issue was reported to the curl project on April 19, 2023. We contacted distros@openwall on May 9, 2023. libcurl 8.1.0 was released on May 17 2023, coordinated with the publication of this advisory.
