https://notcve.org/view.php?id=CVE-2021-22931
Node.js before 16.6.0, 14.17.4, and 12.22.4 is vulnerable to Remote Code Execution, XSS, Application crashes due to missing input validation of host names returned by Domain Name Servers in Node.js dns library which can lead to output of wrong hostnames (leading to Domain Hijacking) and injection vulnerabilities in applications using the library. Node.js versiones anteriores a 16.6.0, 14.17.4 y 12.22.4, es vulnerable a una Ejecución de Código Remota , ataques de tipo XSS, bloqueo de Aplicaciones debido a una falta de comprobación de entrada de los nombres de host devueltos por los Servidores de Nombres de Dominio en la librería dns de Node.js, que puede conllevar a la salida de nombres de host erróneos (conllevando al Secuestro de Dominio) y vulnerabilidades de inyección en aplicaciones que usan la librería. A flaw was found in Node.js. These vulnerabilities include remote code execution, Cross-site scripting (XSS), application crashes due to missing input validation of hostnames returned by Domain Name Servers in the Node.js DNS library, which can lead to the output of wrong hostnames (leading to Domain hijacking) and injection vulnerabilities in applications using the library. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://hackerone.com/reports/1178337 https://nodejs.org/en/blog/vulnerability/aug-2021-security-releases https://security.gentoo.org/glsa/202401-02 https://security.netapp.com/advisory/ntap-20210923-0001 https://security.netapp.com/advisory/ntap-20211022-0003 https://www.oracle.com/security-alerts/cpujan2022.html https://www.oracle.com/security-alerts/cpujul2022.html https://www.oracle.com/security-alerts/cpuoct2021.html https:&# • CWE-20: Improper Input Validation CWE-170: Improper Null Termination •
CVSS: 6.8EPSS: 0%CPEs: 35EXPL: 1CVE-2021-3672 – c-ares: Missing input validation of host names may lead to domain hijacking
https://notcve.org/view.php?id=CVE-2021-3672
A flaw was found in c-ares library, where a missing input validation check of host names returned by DNS (Domain Name Servers) can lead to output of wrong hostnames which might potentially lead to Domain Hijacking. The highest threat from this vulnerability is to confidentiality and integrity as well as system availability. Se ha encontrado un fallo en la biblioteca c-ares, en la que una falta de comprobación de la comprobación de entrada de los nombres de host devueltos por los DNS (Servidores de Nombres de Dominio) puede conllevar a una salida de nombres de host erróneos, que podría conllevar potencialmente a un Secuestro de Dominios. La mayor amenaza de esta vulnerabilidad es para la confidencialidad e integridad, así como para la disponibilidad del sistema • https://bugzilla.redhat.com/show_bug.cgi?id=1988342 https://c-ares.haxx.se/adv_20210810.html https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://security.gentoo.org/glsa/202401-02 https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2021-3672 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

CVSS: 5.3EPSS: 0%CPEs: 4EXPL: 1CVE-2021-22918 – libuv: out-of-bounds read in uv__idna_toascii() can lead to information disclosures or crashes
https://notcve.org/view.php?id=CVE-2021-22918
Node.js before 16.4.1, 14.17.2, 12.22.2 is vulnerable to an out-of-bounds read when uv__idna_toascii() is used to convert strings to ASCII. The pointer p is read and increased without checking whether it is beyond pe, with the latter holding a pointer to the end of the buffer. This can lead to information disclosures or crashes. This function can be triggered via uv_getaddrinfo(). Node.js versiones anteriores a 16.4.1, 14.17.2, 12.22.2, es vulnerable a una lectura fuera de límites cuando la función uv__idna_toascii() es usada para convertir cadenas a ASCII. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://hackerone.com/reports/1209681 https://nodejs.org/en/blog/vulnerability/july-2021-security-releases https://security.gentoo.org/glsa/202401-23 https://security.netapp.com/advisory/ntap-20210805-0003 https://access.redhat.com/security/cve/CVE-2021-22918 https://bugzilla.redhat.com/show_bug.cgi?id=1979338 • CWE-125: Out-of-bounds Read •
CVSS: 7.4EPSS: 0%CPEs: 56EXPL: 0CVE-2021-3450 – CA certificate check bypass with X509_V_FLAG_X509_STRICT
https://notcve.org/view.php?id=CVE-2021-3450
The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a certificate chain. It is not set by default. Starting from OpenSSL version 1.1.1h a check to disallow certificates in the chain that have explicitly encoded elliptic curve parameters was added as an additional strict check. An error in the implementation of this check meant that the result of a previous check to confirm that certificates in the chain are valid CA certificates was overwritten. This effectively bypasses the check that non-CA certificates must not be able to issue other certificates. • http://www.openwall.com/lists/oss-security/2021/03/27/1 http://www.openwall.com/lists/oss-security/2021/03/27/2 http://www.openwall.com/lists/oss-security/2021/03/28/3 http://www.openwall.com/lists/oss-security/2021/03/28/4 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=2a40b7bc7b94dd7de897a74571e7024f0cf0d63b https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44845 https://kc.mc • CWE-295: Improper Certificate Validation •
