Summary

CVE-2024-33900 is a medium-severity Cleartext Storage of Sensitive Information in Memory (CWE-316) vulnerability in Keepassxc Keepassxc. Its CVSS base score is 6.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique OS Credential Dumping (T1003); ranked at the 27th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and SC-39 (Process Isolation) — see the control section below for these in your framework.

Vulnerability Data

KeePassXC 2.7.7 allows an attacker (who has the privileges of the victim) to recover cleartext credentials via a memory dump. NOTE: the vendor disputes this because memory-management constraints make this unavoidable in the current design and other realistic designs.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement partial match

Access enforcement limits which subjects can read memory locations holding the cleartext data.

SC-39 Process Isolation partial match

Process isolation confines the cleartext data to its own execution domain, shrinking exposure.

SC-4 Information in Shared System Resources partial match

Prevents unintended transfer of the cleartext contents through shared memory resources.

PR.DS-10 mostly match
prevents

Explicitly calls for removing confidential data from process memory, directly mitigating cleartext storage.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect cleartext secrets in memory dumps or debug output.

A.8.10 Information deletion partial match
degrades

Secure deletion practices reduce residual cleartext after use, but do not prevent initial storage.

A.8.12 Data leakage prevention partial match
mitigates

DLP tooling can monitor and block processes that leave sensitive data unencrypted in memory.

A.8.24 Use of cryptography partial match
prevents

Cryptographic controls can mandate encryption of sensitive data in memory, directly reducing cleartext exposure.

A.8.25 Secure development life cycle partial match
prevents

Secure-SDLC processes include memory-handling reviews that catch this weakness.

A.8.28 Secure coding partial match
prevents

Secure-coding standards explicitly require avoiding plaintext storage of secrets in RAM.
