CVE-2012-1248
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 · uneditedapp/config/core.php in baserCMS 1.6.15 and earlier does not properly handle installations in shared-hosting environments, which allows remote attackers to hijack sessions by leveraging administrative access to a different domain.
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 confidenceIn baserCMS 1.6.15 and earlier, the app/config/core.php file contains session configuration that does not properly isolate sessions in shared-hosting environments. When multiple domains share the same server, an attacker with administrative access to one domain can potentially hijack sessions from other domains hosted on the same server due to improper session cookie path or save_path settings.

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.
-
Determine baserCMS versionLocate the version file in your baserCMS installation - typically in a config file or version.php within the app directoryAffected if The installed version is 1.6.15 or earlier, or matches any of these: 1.5.4, 1.5.5, 1.5.6, 1.5.7, 1.5.8, 1.5.9, 1.6.0, 1.6.1, 1.6.2, 1.6.3, 1.6.4
-
Locate the core.php configuration fileVerify the presence of app/config/core.php in your baserCMS installation directoryAffected if The file app/config/core.php exists and contains session configuration settings
-
Inspect session.save_path settingOpen app/config/core.php and search for the session.save_path parameter - check if it points to a shared or world-writable directoryAffected if session.save_path is set to a common directory shared across multiple hosted sites, or is not set to a unique per-site path
-
Inspect session.cookie_path and session.cookie_domain settingsIn app/config/core.php, locate session.cookie_path and session.cookie_domain parameters - verify if they restrict cookies to the specific domainAffected if session.cookie_path is set to a generic path like '/' or session.cookie_domain is not set/restricted to the specific domain, allowing cross-domain session access
-
Verify shared hosting environmentConfirm that multiple domains or sites are hosted on the same server and share the same session storage locationAffected if Multiple domains share the same server with overlapping or shared session.save_path configurations
You are affected if running baserCMS version 1.6.15 or earlier with session configuration in app/config/core.php that does not isolate sessions per domain in a shared-hosting environment.
Generated from the published advisory. Verify against your own configuration.
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 dataIsolate session storage by configuring a unique session.save_path directory for each hosted site, set restrictive session.cookie_path and session.cookie_domain parameters in core.php, and consider implementing session regeneration on authentication to prevent session fixation attacks.
