Session-token disclosure via insecure cookie attributes
Published Jul 26, 2021 · Updated Sep 16, 2024
Information disclosure in IBM i2 Analyze 4.3.0 through 4.3.2 allows remote attackers to obtain session tokens over HTTP. Authorization-token and session-cookie responses omit the Secure attribute, so browsers send those cookies to a crafted HTTP link. A user must follow or encounter the link while an attacker can observe the traffic; the reported consequence is limited to cookie disclosure.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=4.3.0
- Affected versionversion=4.3.1
