This can be exploited remotely or via CSRF because the cookie can be placed in an Accept HTTP header in an XMLHttpRequest call to lighttpd.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-78","CWE-119","CWE-352"],"references":["http://packetstormsecurity.com/files/165643/Grandstream-GXV3175-Unauthenticated-Command-Execution.html","http://packetstormsecurity.com/files/165931/Grandstream-GXV31XX-settimezone-Unauthenticated-Command-Execution.html","https://github.com/scarvell/grandstream_exploits","https://www.trustwave.com/en-us/resources/security-resources/security-advisories/?fid=23920&dl=1","http://packetstormsecurity.com/files/165643/Grandstream-GXV3175-Unauthenticated-Command-Execution.html"],"products":["grandstream:gac2500_firmware","grandstream:gvc3202_firmware","grandstream:gxp2200_firmware","grandstream:gxv3240_firmware","grandstream:gxv3275_firmware"],"source":"nvd","synced_at":"2026-10-19T20:55:22.313337056+00:00"},"epss":{"cve":"CVE-2019-10655","score":0.15475,"percentile":0.96805,"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).
