NOTE: it could be argued that this is not a vulnerability in Asterisk, but a class of vulnerabilities that can occur in any program that uses this feature without the associated filtering functionality that is already available.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["http://downloads.digium.com/pub/security/AST-2010-002.html","http://lists.fedoraproject.org/pipermail/package-announce/2010-March/037679.html","http://secunia.com/advisories/38641","http://secunia.com/advisories/39096","http://svn.asterisk.org/svn/asterisk/branches/1.2/README-SERIOUSLY.bestpractices.txt"],"products":["digium:asterisk"],"source":"nvd","synced_at":"2026-10-19T19:55:32.599380760+00:00"},"epss":{"cve":"CVE-2010-0685","score":0.0137,"percentile":0.71918,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
