CVE-2021-23362 – Regular Expression Denial of Service (ReDoS)

https://notcve.org/view.php?id=CVE-2021-23362

The package hosted-git-info before 3.0.8 are vulnerable to Regular Expression Denial of Service (ReDoS) via regular expression shortcutMatch in the fromUrl function in index.js. The affected regular expression exhibits polynomial worst-case time complexity. El paquete hosted-git-info anterior a la versión 3.0.8 es vulnerable a la Denegación de Servicio por Expresión Regular (ReDoS) a través de la expresión regular shortcutMatch en la función fromUrl en index.js. La expresión regular afectada muestra una complejidad de tiempo polinómica en el peor de los casos A regular expression denial of service vulnerability was found in hosted-git-info. If an application allows user input into the affected regular expression (regexp) function, `shortcutMatch` or `fromUrl`, then an attacker could craft a regexp which takes an ever increasing amount of time to process, potentially resulting in a denial of service. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://github.com/npm/hosted-git-info/commit/29adfe5ef789784c861b2cdeb15051ec2ba651a7 https://github.com/npm/hosted-git-info/commit/8d4b3697d79bcd89cdb36d1db165e3696c783a01 https://github.com/npm/hosted-git-info/commit/bede0dc38e1785e732bf0a48ba6f81a4a908eba3 https://github.com/npm/hosted-git-info/commits/v2 https://snyk.io/vuln/SNYK-JAVA-ORGWEBJARSNPM-1088356 https://snyk.io/vuln/SNYK-JS-HOSTEDGITINFO-1088355 https://access.redhat.com/security/cve/CVE&# • CWE-400: Uncontrolled Resource Consumption CWE-1333: Inefficient Regular Expression Complexity •
