CVE-2009-1094· NVD / CVE Program· CNA mitre

Unspecified vulnerability in the LDAP implementation in Java SE Development Kit (JDK) and Java Runtime Environment (JRE) 5.0 Update 17 and e

Noroxi assessment

Priority: Plan (action score 41/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 4.3% (FIRST EPSS); higher than 91.1% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: openjdk-6 (Debian:5.0) 6b11-9.1+lenny2; java-1.6.0-openjdk (Red Hat:enterprise_linux:5::client) 1:1.6.0.0-0.30.b09.el5; java-1.6.0-openjdk-debuginfo (Red Hat:enterprise_linux:5::client) 1:1.6.0.0-0.30.b09.el5.

Add it to your regular patch cycle. Upgrade to openjdk-6 (Debian:5.0) 6b11-9.1+lenny2; java-1.6.0-openjdk (Red Hat:enterprise_linux:5::client) 1:1.6.0.0-0.30.b09.el5; java-1.6.0-openjdk-debuginfo (Red Hat:enterprise_linux:5::client) 1:1.6.0.0-0.30.b09.el5 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Unspecified vulnerability in the LDAP implementation in Java SE Development Kit (JDK) and Java Runtime Environment (JRE) 5.0 Update 17 and earlier; 6 Update 12 and earlier; SDK and JRE 1.3.1_24 and earlier; and 1.4.2_19 and earlier allows remote LDAP servers to execute arbitrary code via unknown vectors related to serialized data.

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.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

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.
