TIBCO JasperReports vulnerability

TIBCO JasperReports Server contains a path traversal vulnerability allowing authenticated users to read sensitive configuration files and web application contents.

Verdict

Today item — known-exploited.

An authenticated attacker can exploit CWE-22 path traversal to access restricted files including configuration data. This vulnerability has been observed in active exploitation and poses a moderate risk to confidentiality of sensitive system information.

Is it exploitable?

— the evidence, ranked above the score
Reported exploitation
2 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 2022-12-29).
CISA KEV ↗Confirmed
Probability (EPSS)
EPSS 0.48753 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 7.7 (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N) · Affected: TIBCO, JasperReports. Confirm exact fixed builds in the vendor advisory.CVSS — CNA-assigned (CVE.org), version 3.0, set at disclosure.
CVE.org ↗Reported
Weakness (CWE)
Mapped to CWE-22 Path Traversal — weakness family: Path traversal / file.CWE assignment from the public NVD record (may be stale); the weakness class drives how the flaw is exploited.
NVD ↗Reported
CISA SSVC (triage disposition)
Exploitation: active · Automatable: no · Technical Impact: partialCISA's own stakeholder-specific triage inputs, published in the CVE record (CISA Coordinator role). NOTE: this is CISA's three decision points; the final Act/Attend/Track decision also requires a Mission & Well-being input not published here, so no overall decision is asserted.
CISA-ADP ↗Reported
Currency of the record
CISA added this to its KEV catalog 1717 days after the CVE record was published.KEV lag = CISA-KEV dateAdded − CVE.org datePublished; a floor on how long the known-exploited flaw sat in the public record before the federal catalog listed it. Severity/weakness here is CNA- or CISA-assigned (current at disclosure), independent of NVD's analysis backlog.

Who’s exploiting it?

— attribution turns risk into urgency
Attribution 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 board
1

Front door — unauthenticated access narrative 1

Attacker
I authenticate to JasperReports Server using valid credentials.
Business
Legitimate user accounts exist across the organization with varying privilege levels.
2

Keys to the kingdom — privilege/identity takeover narrative 2

Attacker
I craft requests using path traversal sequences to bypass directory restrictions.
Business
Access controls fail to properly validate file paths requested by authenticated sessions.
3

Lateral reach — past segmentation narrative 3

Attacker
I read configuration files and application data outside my intended scope.
Business
Sensitive system settings, database credentials, and API keys are exposed to unauthorized disclosure.
4

Data at risk — exfiltration narrative 4

Attacker
I extract credentials and architectural details from retrieved files.
Business
Attackers gain intelligence to pivot to other systems or escalate privileges within the infrastructure.

What to do

— defensible action
  • Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
