CVE-2007-2277
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 · uneditedSession fixation vulnerability in Plogger allows remote attackers to hijack web sessions by setting the PHPSESSID parameter.
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 confidenceSession fixation vulnerability in Plogger allows remote attackers to hijack web sessions by setting the PHPSESSID parameter. The application does not properly regenerate session IDs after authentication, allowing attackers to pre-establish a session ID that legitimate users then inherit.

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 Plogger installationSearch web server document root for plogger directory or files like 'plogger.php', 'gallery.php', or 'plog-globals.php'. Check for /plogger/ or similar paths in web server configuration.Affected if Plogger software is found running on the server
-
Verify Plogger versionCheck the version file or header in Plogger installation - typically in a version.php file, README, or the admin panel about page. Compare against vendor records if available.Affected if Any version of Plogger is confirmed to be installed (all versions affected)
-
Inspect session initialization codeExamine plog-globals.php or similar core PHP files for session_start() calls. Look for whether session_id() is called before session_start() with a user-supplied value.Affected if Code accepts PHPSESSID parameter without validation, allowing attackers to set session ID
-
Check login behavior for session regenerationReview the login processing code (typically in login.php or authentication functions) for calls to session_regenerate_id() or session_create_id() after successful authentication.Affected if Session ID is not regenerated after login - same ID persists before and after authentication
-
Test for session fixation via URL parameterVisit Plogger login page with a crafted URL containing ?PHPSESSID=attackercontrolledid. After authenticating, verify the session ID remains the attacker-controlled value.Affected if Server accepts and maintains the attacker-specified PHPSESSID through the login process
A user is affected if Plogger is running and accepts a user-controlled PHPSESSID parameter that persists through authentication without regeneration.

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 session ID regeneration on login and validate session identifiers properly to prevent fixation attacks. Ensure PHPSESSID cannot be set via user-controlled input.
