Summary

CVE-2024-50624 is a medium-severity Cleartext Transmission of Sensitive Information (CWE-319) vulnerability in Kde (inferred from references). Its CVSS base score is 5.9 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Network Sniffing (T1040); ranked at the 16th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SC-8 (Transmission Confidentiality and Integrity) — see the control section below for these in your framework.

Vulnerability Data

ispdbservice.cpp in KDE Kmail before 6.2.0 allows man-in-the-middle attackers to trigger use of an attacker-controlled mail server because cleartext HTTP is used for a URL such as http://autoconfig.example.com or http://example.com/.well-known/autoconfig for retrieving the configuration. This is related to kmail-account-wizard.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SC-8 Transmission Confidentiality and Integrity good match

SC-8 directly requires protecting confidentiality of transmitted information, which structurally eliminates cleartext transmission of sensitive data.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.DS-02 full match
blocks

Encryption of data-in-transit directly prevents cleartext transmission while the control also addresses integrity and availability.

A.5.17 Authentication information mostly match
removes
A.8.21 Security of network services mostly match
blocks

A.8.21 mandates identifying/implementing network service security features (explicitly including encryption and connection controls), formulating rules that cover authentication/authorization/monitoring/VPNs, and ensuring providers do the same; this stops cleartext transmission from being exploitable in the large majority of network channels, with a bounded remainder (e.g. internal non-networked flows or unaddressed legacy protocols).

A.5.14 Information transfer partial match
blocks

Mandating cryptographic protection and stronger authentication on public networks stops the transmission of plaintext sensitive information.

A.8.5 Secure authentication partial match
removes
