CVE-2023-6837: Incorrect Authorization in Multiple WSO2 Products via Federated Authentication with JIT Provisioning Leading to User Impersonation

Noroxi assessment

Priority: Monitor (action score 32/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.46% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: org.wso2.carbon.identity.framework:org.wso2.carbon.identity.application.authentication.framework (Maven) 5.20.254; org.wso2.identity.apps:authentication-portal (Maven) 1.6.179.1.

Low priority for now. Upgrade to org.wso2.carbon.identity.framework:org.wso2.carbon.identity.application.authentication.framework (Maven) 5.20.254; org.wso2.identity.apps:authentication-portal (Maven) 1.6.179.1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

Multiple WSO2 products have been identified as vulnerable to perform user impersonatoin using JIT provisioning. In order for this vulnerability to have any impact on your deployment, following conditions must be met: * An IDP configured for federated authentication and JIT provisioning enabled with the "Prompt for username, password and consent" option. * A service provider that uses the above IDP for federated authentication and has the "Assert identity using mapped local subject identifier" flag enabled. Attacker should have: * A fresh valid user account in the federated IDP that has not been used earlier. * Knowledge of the username of a valid user in the local IDP. When all preconditions are met, a malicious actor could use JIT provisioning flow to perform user impersonation.
