FAUCET Score

CVE-2023-33847 is a low-severity vulnerability affecting IBM TXSeries for Multiplatforms and CICS TX products, where authorization tokens and session cookies lack the "secure" attribute. This allows attackers to potentially intercept cookie values via insecure HTTP links, leading to a low impact on confidentiality.
