OSGeo GeoServer vulnerability
OSGeo GeoServer improperly neutralizes directives in dynamically evaluated code, allowing unauthenticated remote code execution through unsafe XPath expression evaluation of property names.
Verdict
Today item — known-exploited.
Unauthenticated attackers can exploit unsafe XPath evaluation in GeoServer to execute arbitrary code. The high EPSS score and active exploitation in the wild indicate immediate risk to exposed instances regardless of authentication posture.
01
Is it exploitable?
— the evidence, ranked above the scoreExploit available
Fully weaponized — public exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported exploitation
740 independent public reports of in-the-wild exploitation are cataloged.Distinct reporting sources (vendor, incident response, government); open them for the underlying claims.
Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2024-07-15).
Probability (EPSS)
EPSS 0.99813 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: OSGeo, GeoServer. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-95 Eval Injection — weakness family: Injection.CWE assignment from the public NVD record; the weakness class drives how the flaw is exploited.
02
Who’s exploiting it?
— attribution turns risk into urgencyAttribution not established
No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.
03
Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1
Attacker
I craft a malicious request containing specially formatted property names that are evaluated as XPath expressions by the vulnerable GeoServer instance.
Business
Attackers gain unauthenticated code execution on internet-facing GeoServer deployments, enabling full system compromise and data exfiltration.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I inject code through the XPath evaluation mechanism to establish persistence or pivot to internal network resources.
Business
Compromised GeoServer instances become beachheads for lateral movement within enterprise geospatial infrastructure and connected systems.
04
What to do
— defensible action- Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
Say it to the boardA vulnerability with this evidence profile is a defensible budget line, not a backlog ticket — fund the change against the proof above.
