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-2017-7512
Red Hat 3scale (aka RH-3scale) API Management Platform (AMP) before 2.0.0 would permit creation of an access token without a client secret. An attacker could use this flaw to circumvent authentication controls and gain access to restricted APIs. NOTE: some sources have a typo in which CVE-2017-7512 maps to an OpenVPN vulnerability. The proper CVE ID for that OpenVPN vulnerability is CVE-2017-7521. Specifically, CVE-2017-7521 is the correct CVE ID for TWO closely related findings in OpenVPN. • https://access.redhat.com/errata/RHSA-2017:1712 https://access.redhat.com/security/cve/cve-2017-7512 https://bugzilla.redhat.com/show_bug.cgi?id=1457997 https://access.redhat.com/security/cve/CVE-2017-7512 • CWE-863: Incorrect Authorization •
