Vulnerability AssessmentAI

Exploitation Exploitation requires only network reachability to a deployed itsourcecode Online House Rental System 1.0 instance with the /ajax.php endpoint exposed (the application's default routing); per CVSS AV:N/AC:L/PR:N/UI:N no authentication, user interaction, or non-default configuration is needed beyond running the shipped login workflow. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:N indicates remote, low-complexity, unauthenticated exploitation against an exposed login endpoint, supporting the 7.3 base score with partial CIA impact (C:L/I:L/A:L). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An unauthenticated attacker locates an internet-exposed Online House Rental System instance, then submits a crafted POST request to /ajax.php?action=login with a Username payload such as admin' OR '1'='1'-- to bypass authentication or extract data via UNION/error-based techniques. Because a public PoC is published on GitHub (zhengdexu-bot/zhengdexu issues/3), attackers can copy-paste working requests, enumerate users, dump credentials, or pivot to administrative functions with minimal skill.
Remediation No vendor-released patch identified at time of analysis; the VulDB entry (https://vuldb.com/vuln/367529) and exploit reference (https://github.com/zhengdexu-bot/zhengdexu/issues/3) do not cite a fixed version from itsourcecode. … Detailed patch versions, workarounds, and compensating controls in full report.
