The key identification field (\"kid\") of the IdP's HTTP response message (\"WLS-Response\") can be manipulated by an attacker. The \"kid\" field is not signed like the rest of the message, and manipulation is therefore trivial. The \"kid\" field should only ever represent an integer. However, it is possible to provide any string value. An attacker could use this to their advantage to force the application agent to load the RSA public key required for message integrity checking from an unintended location.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-22"],"references":["https://doi.org/10.1007/978-3-030-03251-7_1","https://github.com/grymer/CVE","https://doi.org/10.1007/978-3-030-03251-7_1","https://github.com/grymer/CVE"],"products":["cam:the_university_of_cambridge_web_authentication_system_apache_authentication_agent"],"source":"nvd","synced_at":"2026-10-19T20:56:19.218283075+00:00"},"epss":{"cve":"CVE-2015-9287","score":0.01987,"percentile":0.80611,"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).
