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 · unedited
Unspecified vulnerability in the Oracle Secure Backup component in Oracle Secure Backup 10.2.0.3 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors. NOTE: the previous information was obtained from the July 2009 Oracle CPU. Oracle has not commented on claims from an independent researcher that this vulnerability allows attackers to bypass authentication via unknown vectors involving the username parameter and login.php.

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 confidence

Authentication bypass vulnerability in Oracle Secure Backup 10.2.0.3 allows remote attackers to bypass authentication mechanisms via unknown vectors involving the username parameter in login.php, granting unauthorized access to the backup system and compromising confidentiality, integrity, and availability.

MitigationApply the July 2009 Oracle Critical Patch Update (CPU) or subsequent patches for Oracle Secure Backup to address the authentication bypass. If patching is not feasible, restrict network access to the login.php interface and implement additional authentication controls such as VPN or IP whitelisting.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify Oracle Secure Backup installation
    Locate Oracle Secure Backup binaries, services, or web interface. Common installation paths include $ORACLE_HOME/osb or check for 'osb' service processes. Check for the web server component typically on ports 443 or 8080.
    Affected if Oracle Secure Backup is present on the system
  2. Confirm installed version equals 10.2.0.3
    Query the installed version through the Oracle Secure Backup administrative interface, check the binary version (often via 'obtool --version' or similar), or review Oracle inventory files. Compare your version to the affected version 10.2.0.3.
    Affected if The installed version is exactly 10.2.0.3
  3. Check login.php web accessibility
    Determine if the Oracle Secure Backup web interface login.php (typically at /login.php or /osb/login.php) is exposed to network access. Test connectivity to the web endpoint.
    Affected if The login.php interface is network-accessible from untrusted networks
  4. Verify authentication configuration
    Review Oracle Secure Backup authentication settings through the administrative console or configuration files. Check whether default or weak authentication methods are in use.
    Affected if Authentication is handled solely by the built-in login.php mechanism without additional controls

A user is affected if Oracle Secure Backup version 10.2.0.3 is installed AND the login.php web interface is network-accessible, allowing remote attackers to bypass authentication.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply the July 2009 Oracle Critical Patch Update (CPU) or subsequent patches for Oracle Secure Backup to address the authentication bypass. If patching is not feasible, restrict network access to the login.php interface and implement additional authentication controls such as VPN or IP whitelisting.

Recommended fix Moderate confidence

Apply July 2009 CPU patch, then upgrade to latest supported Oracle Secure Backup release

  1. Apply Oracle Critical Patch Update (CPU) July 2009 which addresses CVE-2009-1977 for Oracle Secure Backup 10.2.0.3
  2. After applying the July 2009 CPU, upgrade to a more recent supported release of Oracle Secure Backup (Oracle recommends staying current with quarterly CPU releases)
  3. Verify the authentication bypass vulnerability is remediated by testing login.php with the username parameter
Caveat Oracle quarterly CPUs are cumulative; ensure compatibility with existing Oracle Secure Backup infrastructure and review Oracle Secure Backup release notes for any configuration changes
