CVE-2007-3907
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 · uneditedUnspecified vulnerability in login.pl in LedgerSMB 1.2.0 through 1.2.6 allows remote attackers to bypass authentication and perform certain actions as an arbitrary user via unspecified vectors involving a URL with a redirect parameter value, along with a callback parameter containing an escaped URL that specifies the action.
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 confidenceAuthentication bypass vulnerability in login.pl of LedgerSMB 1.2.0-1.2.6 allows remote attackers to execute arbitrary actions as any user by manipulating a redirect parameter combined with a callback parameter containing an escaped URL that specifies the target action, bypassing the normal authentication mechanism entirely.

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 installed LedgerSMB versionLocate the LedgerSMB installation directory and check the version file, or query the application's version information through its web interface or command-line interface if available.Affected if The installed version is 1.2.0, 1.2.1, 1.2.2, 1.2.3, 1.2.4, 1.2.5, or 1.2.6.
-
Verify login.pl exists in the applicationCheck for the presence of the login.pl script in the web application's cgi-bin or web directory. This is the component containing the vulnerability.Affected if The login.pl file exists in the web-accessible directories of the LedgerSMB installation.
-
Confirm the application is network-accessibleDetermine whether the LedgerSMB web interface is exposed to untrusted networks or the internet. Check network configuration, firewall rules, or web server bindings.Affected if The application is accessible from untrusted network locations (such as the internet or untrusted internal networks).
A user is affected if they are running LedgerSMB versions 1.2.0 through 1.2.6 with login.pl accessible over a network, as this combination allows the authentication bypass through manipulated redirect/callback parameters.

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 dataUpgrade to LedgerSMB 1.2.7 or later which contains the patch for this vulnerability. Until patched, consider restricting network access to the application or implementing web application firewall rules to block suspicious URL patterns with redirect/callback parameters.
