CVE-2023-22071· NVD / CVE Program· CNA oracle

Vulnerability in the PL/SQL component of Oracle Database Server.

Vulnerability in the PL/SQL component of Oracle Database Server. Supported versions that are affected are 19.3-19.20 and 21.3-21.11. Easily exploitable vulnerability allows high privileged attacker having Create Session, Execute on sys.utl_http privilege with network access via Oracle Net to compromise PL/SQL. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in PL/SQL, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of PL/SQL accessible data as well as unauthorized read access to a subset of PL/SQL accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of PL/SQL. CVSS 3.1 Base Score 5.9 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:L).

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

EPSS, last 120 days

FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

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.
