The filelog parameter is passed directly into a backtick-delimited exec() call without sanitation. An authenticated attacker can inject arbitrary shell commands, resulting in remote code execution as the root user. ZEN Load Balancer is the predecessor of ZEVENET and SKUDONET. The affected versions (2.0 and 3.0-rc1) are no longer supported. SKUDONET CE is the current community-maintained successor.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","score":9.4},"cvss_v3":null,"cwes":["CWE-78"],"references":["https://raw.githubusercontent.com/rapid7/metasploit-framework/master/modules/exploits/linux/http/zen_load_balancer_exec.rb","https://web.archive.org/web/20111015031540/http://www.zenloadbalancer.com/","https://web.archive.org/web/20221203195056/https://itsecuritysolutions.org/2012-09-21-ZEN-Load-Balancer-v2.0-and-v3.0-rc1-multiple-vulnerabilities/","https://www.exploit-db.com/exploits/21849","https://www.fortiguard.com/encyclopedia/ips/33335/zen-load-balancer-filelog-command-execution"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:06:45.861874017+00:00"},"epss":{"cve":"CVE-2012-10039","score":0.03418,"percentile":0.88897,"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).
