Unspecified vulnerability in the Network Authentication component in Oracle Database 10.1.0.5 and 10.2.0.4 allows remote attackers to affect

Noroxi assessment

Priority: This week (action score 63/100)

  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 76.3% (FIRST EPSS); higher than 99.5% of all records.
  • No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Don’t wait for the next maintenance window. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

Unspecified vulnerability in the Network Authentication component in Oracle Database 10.1.0.5 and 10.2.0.4 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors. NOTE: the previous information was obtained from the October 2009 CPU. Oracle has not commented on claims from an independent researcher that this is related to improper validation of the AUTH_SESSKEY parameter length that leads to arbitrary code execution.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
