Attackers can exploit the verbatim write of unvalidated strings into the pppd options file via write_config_option() to inject the plugin directive, causing the privileged pppd process to load an attacker-controlled shared object and achieve arbitrary code execution as root.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.5},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8},"cwes":["CWE-88"],"references":["https://github.com/nm-l2tp/NetworkManager-l2tp/commit/64879ce0ad866f7c9a45babe4d95731a916ea00f","https://github.com/nm-l2tp/NetworkManager-l2tp/security/advisories/GHSA-rp84-8h2r-5xc3","https://www.vulncheck.com/advisories/networkmanager-l2tp-privilege-escalation-via-pppd-plugin-injection"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-93337","score":0.00148,"percentile":0.04002,"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).
