CVSS: 7.5EPSS: 83%CPEs: 444EXPL: 7CVE-2023-44487 – HTTP/2 Rapid Reset Attack Vulnerability
https://notcve.org/view.php?id=CVE-2023-44487
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. El protocolo HTTP/2 permite una denegación de servicio (consumo de recursos del servidor) porque la cancelación de solicitudes puede restablecer muchas transmisiones rápidamente, como se explotó en la naturaleza entre agosto y octubre de 2023. A flaw was found in handling multiplexed streams in the HTTP/2 protocol. A client can repeatedly make a request for a new multiplex stream and immediately send an RST_STREAM frame to cancel it. This creates extra work for the server setting up and tearing down the streams while not hitting any server-side limit for the maximum number of active streams per connection, resulting in a denial of service due to server resource consumption. • https://github.com/imabee101/CVE-2023-44487 https://github.com/studiogangster/CVE-2023-44487 https://github.com/bcdannyboy/CVE-2023-44487 https://github.com/sigridou/CVE-2023-44487- https://github.com/ByteHackr/CVE-2023-44487 https://github.com/ReToCode/golang-CVE-2023-44487 http://www.openwall.com/lists/oss-security/2023/10/13/4 http://www.openwall.com/lists/oss-security/2023/10/13/9 http://www.openwall.com/lists/oss-security/2023/10/18/4 http://www. • CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2023-27537
A double free vulnerability exists in libcurl <8.0.0 when sharing HSTS data between separate "handles". This sharing was introduced without considerations for do this sharing across separate threads but there was no indication of this fact in the documentation. Due to missing mutexes or thread locks, two threads sharing the same HSTS data could end up doing a double-free or use-after-free. • https://hackerone.com/reports/1897203 https://security.gentoo.org/glsa/202310-12 https://security.netapp.com/advisory/ntap-20230420-0010 • CWE-415: Double Free •

https://notcve.org/view.php?id=CVE-2023-27534
A path traversal vulnerability exists in curl <8.0.0 SFTP implementation causes the tilde (~) character to be wrongly replaced when used as a prefix in the first path element, in addition to its intended use as the first element to indicate a path relative to the user's home directory. Attackers can exploit this flaw to bypass filtering or execute arbitrary code by crafting a path like /~2/foo while accessing a server with a specific user. • https://hackerone.com/reports/1892351 https://lists.debian.org/debian-lts-announce/2024/03/msg00016.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/36NBD5YLJXXEDZLDGNFCERWRYJQ6LAQW https://security.gentoo.org/glsa/202310-12 https://security.netapp.com/advisory/ntap-20230420-0012 https://access.redhat.com/security/cve/CVE-2023-27534 https://bugzilla.redhat.com/show_bug.cgi?id=2179069 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 5.5EPSS: 0%CPEs: 17EXPL: 1CVE-2023-27538 – curl: SSH connection too eager reuse still
https://notcve.org/view.php?id=CVE-2023-27538
An authentication bypass vulnerability exists in libcurl prior to v8.0.0 where it reuses a previously established SSH connection despite the fact that an SSH option was modified, which should have prevented reuse. libcurl maintains a pool of previously used connections to reuse them for subsequent transfers if the configurations match. However, two SSH settings were omitted from the configuration check, allowing them to match easily, potentially leading to the reuse of an inappropriate connection. • https://hackerone.com/reports/1898475 https://lists.debian.org/debian-lts-announce/2023/04/msg00025.html https://security.gentoo.org/glsa/202310-12 https://security.netapp.com/advisory/ntap-20230420-0010 https://access.redhat.com/security/cve/CVE-2023-27538 https://bugzilla.redhat.com/show_bug.cgi?id=2179103 • CWE-287: Improper Authentication CWE-305: Authentication Bypass by Primary Weakness •

https://notcve.org/view.php?id=CVE-2022-23437
There's a vulnerability within the Apache Xerces Java (XercesJ) XML parser when handling specially crafted XML document payloads. This causes, the XercesJ XML parser to wait in an infinite loop, which may sometimes consume system resources for prolonged duration. This vulnerability is present within XercesJ version 2.12.1 and the previous versions. Se presenta una vulnerabilidad en el analizador XML de Apache Xerces Java (XercesJ) cuando maneja cargas útiles de documentos XML especialmente diseñados. Esto causa que el analizador XML de XercesJ espere en un bucle infinito, lo que a veces puede consumir recursos del sistema durante un tiempo prolongado. • http://www.openwall.com/lists/oss-security/2022/01/24/3 https://lists.apache.org/thread/6pjwm10bb69kq955fzr1n0nflnjd27dl https://security.netapp.com/advisory/ntap-20221028-0005 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2022-23437 https://bugzilla.redhat.com/show_bug.cgi?id=2047200 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
