CVE-2023-3826
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability has been found in IBOS OA 4.5.5 and classified as critical. Affected by this vulnerability is an unknown functionality of the file /?r=recruit/resume/edit&op=status of the component Interview Handler. The manipulation of the argument resumeid leads to sql injection. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-235147. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceSQL injection vulnerability in IBOS OA 4.5.5's Interview Handler component at the /?r=recruit/resume/edit&op=status endpoint. The resumeid parameter is not properly sanitized, allowing remote unauthenticated attackers to inject arbitrary SQL commands.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm IBOS OA installationIdentify if IBOS OA (Office Automation system) is deployed in your environment by checking for IBOS-specific web directories, login pages, or service processes.Affected if IBOS OA is not installed - you are not affected
-
Verify IBOS OA versionCheck the installed IBOS OA version. Common methods include: accessing /static/version.js, checking version info in the admin panel, or reviewing installation files. The affected version is specifically 4.5.5.Affected if The installed version is exactly 4.5.5 - proceed to next check; otherwise you are not affected
-
Check if recruit module is enabledIn the IBOS OA admin panel, verify whether the Recruit module (recruitment management) is enabled. This module contains the vulnerable resume/edit functionality.Affected if The Recruit module is enabled - the vulnerable endpoint is accessible; if disabled you are likely not affected
-
Confirm endpoint accessibilityVerify the vulnerable endpoint /?r=recruit/resume/edit&op=status is accessible by attempting to access it or checking URL routing configuration. The vulnerability is exploitable without authentication.Affected if The endpoint is reachable from your network without authentication - exploitation is possible
You are affected only if IBOS OA version 4.5.5 is installed with the Recruit module enabled, making the /?r=recruit/resume/edit&op=status endpoint accessible for SQL injection via the resumeid parameter.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement input validation and parameterized queries/prepared statements for the resumeid parameter. As the vendor is unresponsive, restrict network access to the IBOS OA system via firewall/WAF and monitor for exploitation attempts until a patch is available.
