CVSS: 9.3EPSS: 2%CPEs: 21EXPL: 1CVE-2020-8174 – nodejs: memory corruption in napi_get_value_string_* functions
https://notcve.org/view.php?id=CVE-2020-8174
napi_get_value_string_*() allows various kinds of memory corruption in node < 10.21.0, 12.18.0, and < 14.4.0. La función napi_get_value_string_*(), permite varios tipos de corrupción de memoria en node versiones anteriores a 10.21.0, 12.18.0 y versiones anteriores a 14.4.0 A flaw was found in nodejs. Calling napi_get_value_string_latin1(), napi_get_value_string_utf8(), or napi_get_value_string_utf16() with a non-NULL buf, and a bufsize of 0 will cause the entire string value to be written to buf, probably overrunning the length of the buffer. • https://hackerone.com/reports/784186 https://security.gentoo.org/glsa/202101-07 https://security.netapp.com/advisory/ntap-20201023-0003 https://www.oracle.com//security-alerts/cpujul2021.html https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujan2021.html https://www.oracle.com/security-alerts/cpuoct2020.html https://access.redhat.com/security/cve/CVE-2020-8174 https://bugzilla.redhat.com/show_bug.cgi?id=1845256 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-191: Integer Underflow (Wrap or Wraparound) •

Keep-alive HTTP and HTTPS connections can remain open and inactive for up to 2 minutes in Node.js 6.16.0 and earlier. Node.js 8.0.0 introduced a dedicated server.keepAliveTimeout which defaults to 5 seconds. The behavior in Node.js 6.16.0 and earlier is a potential Denial of Service (DoS) attack vector. Node.js 6.17.0 introduces server.keepAliveTimeout and the 5-second default. Las conexiones HTTP y HTTPS "keep-alive" pueden permanecer abiertas y inactivas durante hasta 2 minutos en Node.js en versiones 6.16.0 y anteriores. • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00046.html https://nodejs.org/en/blog/vulnerability/february-2019-security-releases https://security.gentoo.org/glsa/202003-48 https://security.netapp.com/advisory/ntap-20190502-0008 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 7.5EPSS: 1%CPEs: 5EXPL: 0CVE-2019-5737 – nodejs: Insufficient Slowloris fix causing DoS via server.headersTimeout bypass
https://notcve.org/view.php?id=CVE-2019-5737
In Node.js including 6.x before 6.17.0, 8.x before 8.15.1, 10.x before 10.15.2, and 11.x before 11.10.1, an attacker can cause a Denial of Service (DoS) by establishing an HTTP or HTTPS connection in keep-alive mode and by sending headers very slowly. This keeps the connection and associated resources alive for a long period of time. Potential attacks are mitigated by the use of a load balancer or other proxy layer. This vulnerability is an extension of CVE-2018-12121, addressed in November and impacts all active Node.js release lines including 6.x before 6.17.0, 8.x before 8.15.1, 10.x before 10.15.2, and 11.x before 11.10.1. En Node.js, que incluye la versión 6.x en versiones anteriores a la 6.17.0, 8.x en versiones anteriores a la 8.15.1, 10.x en versiones anteriores a la 10.15.2 y 11.x en versiones anteriores a la 11.10.1, un atacante puede provocar una denegación de servicio (DoS) instalando una conexión HTTP o HTTPS en modo keep-alive y enviando encabezados muy lentamente. • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00046.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00059.html https://access.redhat.com/errata/RHSA-2019:1821 https://nodejs.org/en/blog/vulnerability/february-2019-security-releases https://security.gentoo.org/glsa/202003-48 https://security.netapp.com/advisory/ntap-20190502-0008 https://access.redhat.com/security/cve/CVE-2019-5737 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
CVSS: 5.9EPSS: 1%CPEs: 180EXPL: 0CVE-2019-1559 – 0-byte record padding oracle
https://notcve.org/view.php?id=CVE-2019-1559
If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00046.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00047.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00049.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00080.html http://www.securityfocus.com/bid/107174 https://access. • CWE-203: Observable Discrepancy CWE-325: Missing Cryptographic Step •

Un atacante puede provocar una denegación de servicio (DoS) enviando cabeceras muy lentamente, manteniendo las conexiones HTTP o HTTPS y los recursos asociados vivos durante un largo período de tiempo. It was found that Node.js HTTP server was vulnerable to a Slowloris type attack. An attacker could make long lived connections by sending bytes very slowly to the server, saturating its resource and possibly resulting in a denial of service. • http://www.securityfocus.com/bid/106043 https://access.redhat.com/errata/RHSA-2019:1821 https://nodejs.org/en/blog/vulnerability/november-2018-security-releases https://security.gentoo.org/glsa/202003-48 https://access.redhat.com/security/cve/CVE-2018-12122 https://bugzilla.redhat.com/show_bug.cgi?id=1661005 • CWE-400: Uncontrolled Resource Consumption •
