{"cve":"CVE-2025-53632","nvd":{"published":"2025-07-10T20:15:27.673","modified":"2026-06-17T09:38:36.530","status":"Analyzed","description":"Chall-Manager is a platform-agnostic system able to start Challenges on Demand of a player. When decoding a scenario (i.e. a zip archive), the path of the file to write is not checked, potentially leading to zip slips. Exploitation does not require authentication nor authorization, so anyone can exploit it. It should nonetheless not be exploitable as it is highly recommended to bury Chall-Manager deep within the infrastructure due to its large capabilities, so no users could reach the system. Patch has been implemented by commit 47d188f and shipped in v0.1.4.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N","score":8.8},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","score":9.1},"cwes":["CWE-22"],"references":["https://github.com/ctfer-io/chall-manager/commit/47d188fda5e3f86285e820f12ad9fb6f9930662c","https://github.com/ctfer-io/chall-manager/releases/tag/v0.1.4","https://github.com/ctfer-io/chall-manager/security/advisories/GHSA-3gv2-v3jx-r9fh"],"products":["ctfer-io:chall-manager"],"source":"nvd","synced_at":"2026-10-19T22:04:28.436527499+00:00"},"epss":{"cve":"CVE-2025-53632","score":0.00822,"percentile":0.57328,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-3gv2-v3jx-r9fh","url":"https://osv.dev/vulnerability/GHSA-3gv2-v3jx-r9fh","summary":"Chall-Manager is vulnerable to Path Traversal when extracting/decoding a zip archive","modified":"2025-08-14T22:21:05Z","packages":[{"ecosystem":"Go","name":"github.com/ctfer-io/chall-manager","purl":"pkg:golang/github.com/ctfer-io/chall-manager","ranges":["<0.1.4"],"fixed":["0.1.4"]}]},{"id":"GO-2025-3808","url":"https://osv.dev/vulnerability/GO-2025-3808","summary":"Chall-Manager is vulnerable to Path Traversal when extracting/decoding a zip archive in github.com/ctfer-io/chall-manager","modified":"2026-03-03T04:56:42.899792Z","packages":[{"ecosystem":"Go","name":"github.com/ctfer-io/chall-manager","purl":"pkg:golang/github.com/ctfer-io/chall-manager","ranges":["<0.1.4"],"fixed":["0.1.4"]}]}],"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).
