https://notcve.org/view.php?id=CVE-2017-16024
The sync-exec module is used to simulate child_process.execSync in node versions <0.11.9. Sync-exec uses tmp directories as a buffer before returning values. Other users on the server have read access to the tmp directory, possibly allowing an attacker on the server to obtain confidential information from the buffer/tmp file, while it exists. El módulo sync-exec se emplea para simular child_process.execSync en la versiones de node anteriores a la 0.11.9. Sync-exec emplea directorios tmp como búfer antes de devolver valores. • https://cwe.mitre.org/data/definitions/377.html https://github.com/gvarsanyi/sync-exec/issues/17 https://nodesecurity.io/advisories/310 https://www.owasp.org/index.php/Insecure_Temporary_File • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-377: Insecure Temporary File •
CVSS: 5.3EPSS: 0%CPEs: 7EXPL: 0CVE-2018-7159 – nodejs: HTTP parser allowed for spaces inside Content-Length header values
https://notcve.org/view.php?id=CVE-2018-7159
The HTTP parser in all current versions of Node.js ignores spaces in the `Content-Length` header, allowing input such as `Content-Length: 1 2` to be interpreted as having a value of `12`. The HTTP specification does not allow for spaces in the `Content-Length` value and the Node.js HTTP parser has been brought into line on this particular difference. The security risk of this flaw to Node.js users is considered to be VERY LOW as it is difficult, and may be impossible, to craft an attack that makes use of this flaw in a way that could not already be achieved by supplying an incorrect value for `Content-Length`. Vulnerabilities may exist in user-code that make incorrect assumptions about the potential accuracy of this value compared to the actual length of the data supplied. Node.js users crafting lower-level HTTP utilities are advised to re-check the length of any input supplied after parsing is complete. • https://access.redhat.com/errata/RHSA-2019:2258 https://nodejs.org/en/blog/vulnerability/march-2018-security-releases https://support.f5.com/csp/article/K27228191?utm_source=f5support&%3Butm_medium=RSS https://access.redhat.com/security/cve/CVE-2018-7159 https://bugzilla.redhat.com/show_bug.cgi?id=1561981 • CWE-20: Improper Input Validation CWE-115: Misinterpretation of Input •

https://notcve.org/view.php?id=CVE-2018-7160
The Node.js inspector, in 6.x and later is vulnerable to a DNS rebinding attack which could be exploited to perform remote code execution. An attack is possible from malicious websites open in a web browser on the same computer, or another computer with network access to the computer running the Node.js process. A malicious website could use a DNS rebinding attack to trick the web browser to bypass same-origin-policy checks and to allow HTTP connections to localhost or to hosts on the local network. If a Node.js process with the debug port active is running on localhost or on a host on the local network, the malicious website could connect to it as a debugger, and get full code execution access. El inspector de Node.js, en versiones 6.x y siguientes, es vulnerable a un ataque de reenlace DNS que podría explotarse para ejecutar código de forma remota. • https://nodejs.org/en/blog/vulnerability/march-2018-security-releases https://support.f5.com/csp/article/K63025104?utm_source=f5support&%3Butm_medium=RSS https://www.oracle.com//security-alerts/cpujul2021.html https://access.redhat.com/security/cve/CVE-2018-7160 https://bugzilla.redhat.com/show_bug.cgi?id=1561979 • CWE-20: Improper Input Validation CWE-290: Authentication Bypass by Spoofing CWE-350: Reliance on Reverse DNS Resolution for a Security-Critical Action •

https://notcve.org/view.php?id=CVE-2018-7158
The `'path'` module in the Node.js 4.x release line contains a potential regular expression denial of service (ReDoS) vector. The code in question was replaced in Node.js 6.x and later so this vulnerability only impacts all versions of Node.js 4.x. The regular expression, `splitPathRe`, used within the `'path'` module for the various path parsing functions, including `path.dirname()`, `path.extname()` and `path.parse()` was structured in such a way as to allow an attacker to craft a string, that when passed through one of these functions, could take a significant amount of time to evaluate, potentially leading to a full denial of service. El módulo "path" en la línea de distribución 4.x de Node.js cointiene un vector potencial de denegación de servicio con expresiones regulares (ReDoS). El código en cuestión se reemplazó en Node.js 6.x y siguientes, por lo que esta vulnerabilidad solo impact a todas las versiones de Node.js 4.x. • https://nodejs.org/en/blog/vulnerability/march-2018-security-releases • CWE-185: Incorrect Regular Expression •
CVSS: 7.5EPSS: 4%CPEs: 6EXPL: 0CVE-2018-1000168 – nghttp2: Null pointer dereference when too large ALTSVC frame is received
https://notcve.org/view.php?id=CVE-2018-1000168
nghttp2 version >= 1.10.0 and nghttp2 <= v1.31.0 contains an Improper Input Validation CWE-20 vulnerability in ALTSVC frame handling that can result in segmentation fault leading to denial of service. This attack appears to be exploitable via network client. This vulnerability appears to have been fixed in >= 1.31.1. nghttp2 hasta la versión 1.10.0 y nghttp2 en versiones 1.31.0 y anteriores contienen una vulnerabilidad de validación incorrecta de entradas (CWE-20) en la gestión de tramas ALTSVC que puede resultar en un fallo de segmentación, lo que provoca una denegación de servicio (DoS). Este ataque parece ser explotable mediante un cliente de red. La vulnerabilidad parece haber sido solucionada en la versión 1.31.1 y posteriores. • http://www.securityfocus.com/bid/103952 https://access.redhat.com/errata/RHSA-2019:0366 https://access.redhat.com/errata/RHSA-2019:0367 https://lists.debian.org/debian-lts-announce/2021/10/msg00011.html https://nghttp2.org/blog/2018/04/12/nghttp2-v1-31-1 https://nodejs.org/en/blog/vulnerability/june-2018-security-releases https://access.redhat.com/security/cve/CVE-2018-1000168 https://bugzilla.redhat.com/show_bug.cgi?id=1565035 • CWE-20: Improper Input Validation CWE-476: NULL Pointer Dereference •
