Published: 16 October 2024
Summary
CVE-2024-44762 is a medium-severity Generation of Error Message Containing Sensitive Information (CWE-209) vulnerability in Webmin Usermin. Its CVSS base score is 5.3 (Medium).
Operationally, ranked in the top 5.7% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
CVE-2024-44762 is an information disclosure vulnerability in Webmin Usermin version 2.100 stemming from inconsistent error messages returned during failed login attempts. The flaw, tracked under CWE-209, enables enumeration of valid user accounts through observable differences in responses and carries a CVSS 3.1 base score of 5.3 reflecting network-accessible, low-complexity attack conditions with limited confidentiality impact.
Unauthenticated remote attackers can exploit the issue over the network by submitting crafted login attempts and analyzing the resulting error messages to distinguish between valid and invalid usernames. Successful enumeration provides attackers with a list of active accounts that can be leveraged for further targeted attacks such as credential stuffing or social engineering.
The single available reference does not detail patches or configuration changes. The associated EPSS score has remained in a narrow band between 0.13 and 0.15 with no pronounced upward trajectory after disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Detects error messages that leak sensitive information as evidence of disclosure.
The control directly mitigates generation of error messages containing sensitive authentication details by requiring obscured feedback instead of verbose responses.
Misdirection allows generation of misleading error messages that withhold or falsify sensitive details.
Explicitly requires error messages to avoid including sensitive or exploitable details while still supporting corrective action.
Validation ensures error messages contain only expected, non-sensitive content and blocks leakage via verbose errors.
Fail-safe procedures can be defined to suppress or sanitize error output, reducing generation of messages that contain sensitive information.
