CVE-2022-30076
Published: 16 April 2023
Summary
CVE-2022-30076 is a medium-severity Improper Restriction of Excessive Authentication Attempts (CWE-307) vulnerability in Entab Erp. Its CVSS base score is 5.3 (Medium).
Operationally, ranked in the top 5.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
ENTAB ERP 1.0 is affected by an information disclosure vulnerability that enables enumeration of users' full names. The flaw arises because the application accepts sequential student usernames such as s10000 through s20000 without implementing rate limiting, a condition reflected in its CWE-307 classification and CVSS 3.1 score of 5.3.
Unauthenticated remote attackers can exploit the issue over the network by issuing a series of automated queries against predictable username patterns. Successful enumeration yields only partial identity data and does not directly permit further compromise of confidentiality, integrity, or availability.
Public references consist solely of exploit details published on Packet Storm Security; no vendor advisory, patch, or mitigation guidance is referenced. The associated EPSS score has remained flat at 0.1283 with no material rise 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.
This control directly enforces limits on consecutive invalid logon attempts and automatic response (e.g., lockout) to prevent brute-force exploitation of authentication mechanisms.
Specific conditions can include excessive failed attempts, triggering stronger authentication that restricts brute-force exploitation.
