Attackers can send GET requests to /compress.php with '../' sequences in the 'file' parameter, which is appended to the cache path and passed to readfile(), to read files such as /etc/passwd. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-21.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":8.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-22"],"references":["https://cxsecurity.com/issue/WLB-2018020249","https://github.com/projectdiscovery/nuclei-templates/blob/main/http/vulnerabilities/other/groupoffice-lfi.yaml","https://www.group-office.com/","https://www.vulncheck.com/advisories/intermesh-group-office-3.5.5-path-traversal-via-compress-php"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:28.036610720+00:00"},"epss":{"cve":"CVE-2018-25438","score":0.00536,"percentile":0.44906,"date":"2026-10-25"},"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).
