OnlineVotingSystem before version 1.1.2 hashes user passwords without a salt, which is vulnerable to dictionary attacks. Therefore there is a threat of security breach in the voting system. Without a salt, it is much easier for attackers to pre-compute the hash value using dictionary attack techniques such as rainbow tables to crack passwords. This problem is fixed and published in version 1.1.2. A long randomly generated salt is added to the password hash function to better protect passwords stored in the voting system.","severity":{"version":"3.1","score":5.8,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N","level":"medium","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-11","score":0.00745,"percentile":0.55233,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-759","CWE-916"],"published":"2021-01-21T14:20:16Z","modified":"2026-10-20T14:18:40Z","products":[{"vendor":"dbijaya","product":"onlinevotingsystem"},{"vendor":"onlinevotingsystem_project","product":"onlinevotingsystem"}],"references":[{"url":"https://github.com/dbijaya/OnlineVotingSystem/security/advisories/GHSA-wwg8-372v-v332","tags":["x_refsource_CONFIRM","x_transferred","Third Party Advisory","advisory"]},{"url":"https://github.com/dbijaya/OnlineVotingSystem/commit/0181cb0272857696c8eb3e44fcf6cb014ff90f09","tags":["x_refsource_MISC","x_transferred","Patch","Third Party Advisory","fix"]}],"sources":{"cve":[{"id":"CVE-2021-21253","title":"Use of a One-Way Hash without a Salt in OnlineVotingSystem","description":"OnlineVotingSystem is an open source project hosted on GitHub.
