CVSS: 7.5EPSS: 0%CPEs: 11EXPL: 0CVE-2023-29530 – Laminas Diactoros vulnerable to HTTP Multiline Header Termination
https://notcve.org/view.php?id=CVE-2023-29530
Laminas Diactoros provides PSR HTTP Message implementations. In versions 2.18.0 and prior, 2.19.0, 2.20.0, 2.21.0, 2.22.0, 2.23.0, 2.24.0, and 2.25.0, users who create HTTP requests or responses using laminas/laminas-diactoros, when providing a newline at the start or end of a header key or value, can cause an invalid message. This can lead to denial of service vectors or application errors. The problem has been patched in following versions 2.18.1, 2.19.1, 2.20.1, 2.21.1, 2.22.1, 2.23.1, 2.24.1, and 2.25.1. As a workaround, validate HTTP header keys and/or values, and if using user-supplied values, filter them to strip off leading or trailing newline characters before calling `withHeader()`. • https://github.com/advisories/GHSA-wxmh-65f7-jcvw https://github.com/laminas/laminas-diactoros/security/advisories/GHSA-xv3h-4844-9h36 https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/BPW54QK7ISDALPLP2CKODU4ZIVRYS336 • CWE-20: Improper Input Validation •
CVSS: 7.2EPSS: 0%CPEs: 1EXPL: 0CVE-2022-31109 – HTTP Host Header Attack Vulnerability in laminas-diactoros
https://notcve.org/view.php?id=CVE-2022-31109
laminas-diactoros is a PHP package containing implementations of the PSR-7 HTTP message interfaces and PSR-17 HTTP message factory interfaces. Applications that use Diactoros, and are either not behind a proxy, or can be accessed via untrusted proxies, can potentially have the host, protocol, and/or port of a `Laminas\Diactoros\Uri` instance associated with the incoming server request modified to reflect values from `X-Forwarded-*` headers. Such changes can potentially lead to XSS attacks (if a fully-qualified URL is used in links) and/or URL poisoning. Since the `X-Forwarded-*` headers do have valid use cases, particularly in clustered environments using a load balancer, the library offers mitigation measures only in the v2 releases, as doing otherwise would break these use cases immediately. Users of v2 releases from 2.11.1 can provide an additional argument to `Laminas\Diactoros\ServerRequestFactory::fromGlobals()` in the form of a `Laminas\Diactoros\RequestFilter\RequestFilterInterface` instance, including the shipped `Laminas\Diactoros\RequestFilter\NoOpRequestFilter` implementation which ignores the `X-Forwarded-*` headers. • https://github.com/laminas/laminas-diactoros/commit/25b11d422c2e5dad868f68619888763b30f91e2d https://github.com/laminas/laminas-diactoros/security/advisories/GHSA-8274-h5jp-97vr https://portswigger.net/web-security/host-header • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
