{"id":"CVE-2026-40523","summary":"FrontAccounting \u003c 2.4.20 SQL Injection via reporting/rep710.php","details":"FrontAccounting before 2.4.20 contains a SQL injection vulnerability in the Audit Trail report handler that allows authenticated attackers with SA_GLANALYTIC permission to execute arbitrary SQL queries by injecting malicious code into the PARAM_2 and PARAM_3 POST parameters. Attackers can exploit time-based blind SQL injection through SLEEP() functions that are amplified across JOIN result sets to cause denial of service by exhausting database connections, or extract arbitrary database content through UNION-based injection techniques.","modified":"2026-07-16T03:48:30.793319870Z","published":"2026-06-29T12:29:10.512Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40523.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"fixed":"2.4.20"}]},{"extracted_events":[{"fixed":"2.4.20"}],"source":"CPE_FIELD"},{"extracted_events":[{"fixed":"2.4.20"}],"source":"DESCRIPTION"}],"cna_assigner":"VulnCheck","cwe_ids":["CWE-89"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40523.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40523"},{"type":"ADVISORY","url":"https://sourceforge.net/p/frontaccounting/news/2026/04/release-2420/"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/frontaccounting-sql-injection-via-reporting-rep710-php"},{"type":"FIX","url":"https://github.com/FrontAccountingERP/FA/commit/647a18196caad27f96ea852e993c9e30f815357f"},{"type":"EVIDENCE","url":"https://jivasecurity.com/writeups/frontaccounting-sqli-audit-trail-report-cve-2026-40523"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/frontaccountingerp/fa","events":[{"introduced":"0"},{"fixed":"647a18196caad27f96ea852e993c9e30f815357f"}],"database_specific":{"source":"REFERENCES"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-40523.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
