CVE-2024-42559
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 · uneditedAn issue in the login component (process_login.php) of Hotel Management System commit 79d688 allows attackers to authenticate without providing a valid password.
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 · moderate confidenceThe Hotel Management System's login component (process_login.php) contains an authentication bypass vulnerability that allows attackers to authenticate without providing a valid password. This is a critical flaw in the authentication logic that grants unauthorized access to the system.

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.
-
Identify if Hotel Management System is deployedSearch your web server document root for files or directories related to a hotel management system, or check your application inventory for this applicationAffected if The Hotel Management System is present in your environment
-
Locate process_login.phpSearch for the file process_login.php in your web application's directories, commonly found in the authentication or admin foldersAffected if process_login.php exists in your deployment
-
Examine authentication logic in process_login.phpOpen process_login.php and review the password validation section - look for conditional statements that grant authentication without proper password verification, such as missing else blocks or flawed comparison logicAffected if The code shows authentication is granted without proper password validation
-
Verify login functionality with invalid passwordAttempt to log in using a valid username with an intentionally incorrect password and observe if authentication succeedsAffected if Authentication succeeds with an invalid password
-
Check authentication logs for unauthorized accessReview authentication and access logs for successful logins that may correspond to invalid password attemptsAffected if Log entries show successful logins without valid credentials
You are affected if the Hotel Management System is deployed with process_login.php containing flawed authentication logic that grants access without validating the password.

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 dataThe password validation logic in process_login.php must be reviewed and fixed to properly verify credentials before granting authentication. Ensure proper password hashing and comparison are implemented.
