Apache Tomcat vulnerability
Apache Tomcat path equivalence vulnerability allows remote code execution, information disclosure, or content injection through partial PUT requests.
Verdict
Today item — known-exploited.
A path equivalence flaw in Apache Tomcat enables unauthenticated remote attackers to execute arbitrary code, access sensitive information, or inject malicious content via crafted partial PUT requests. Active exploitation observed in the wild.
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
102 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 2025-04-01).
Probability (EPSS)
EPSS 0.99945 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Apache, Tomcat. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-44 CWE-44, CWE-502 Deserialization of Untrusted Data — 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 partial PUT request that exploits path equivalence to bypass access controls and reach restricted resources.
Business
Attackers gain unauthorized access to application files and system resources without authentication.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I inject malicious code or content into the application through the path equivalence vulnerability.
Business
Compromised application integrity leads to malware distribution, data tampering, and loss of customer trust.
3
Lateral reach — past segmentation narrative 3
Attacker
I execute arbitrary code on the Tomcat server by leveraging the vulnerability in request handling.
Business
Full server compromise enables data exfiltration, lateral movement, and operational disruption.
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.
