Evidence used

  • No CISA KEV confirmation is currently recorded.
  • A structured source references public exploit or proof-of-concept material.
  • EPSS is 3.81% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict local access and enforce least privilege on affected hosts.
  • Increase monitoring for the attack path and post-exploitation behaviour described in the report.

Verification

  1. Confirm that the asset runs Unknown Unknown and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: As exposure requiresRemediation target: Within 365 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

What, why and how

Multiple cross-site scripting (XSS) vulnerabilities in Tikiwiki (aka Tiki CMS/Groupware) 1.9.x allow remote attackers to inject arbitrary web script or HTML via malformed nested HTML tags such as "<scr<script>ipt>" in (1) offset and (2) days parameters in (a) tiki-lastchanges.php, the (3) find and (4) offset parameters in (b) tiki-orphan_pages.php, the (5) offset and (6) initial parameters in (c) tiki-listpages.php, and (7) an unspecified field in (d) tiki-remind_password.php; and allow remote authenticated users with admin privileges to inject arbitrary web script or HTML via (8) an unspecified field in a metatags action in (e) tiki-admin.php, the (9) offset parameter in (f) tiki-admin_rssmodules.php, the (10) offset and (11) max parameters in (g) tiki-syslog.php, the (12) numrows parameter in (h) tiki-adminusers.php, (13) an unspecified field in (i) tiki-adminusers.php, (14) an unspecified field in (j) tiki-admin_hotwords.php, unspecified fields in (15) "Assign new module" and (16) "Create new user module" in (k) tiki-admin_modules.php, (17) an unspecified field in "Add notification" in (l) tiki-admin_notifications.php, (18) the offset parameter in (m) tiki-admin_notifications.php, the (19) Name and (20) Dsn fields in (o) tiki-admin_dsn.php, the (21) offset parameter in (p) tiki-admin_content_templates.php, (22) an unspecified field in "Create new template" in (q) tiki-admin_content_templates.php, and the (23) offset parameter in (r) tiki-admin_chat.php.

Why

Attacker-controlled content can reach a browser as executable script without sufficient output encoding or sanitisation.

How

An attacker operating through the affected interface may attempt exploitation when the stated preconditions are met. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

02

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
Reference recorded

A structured CVE source labels at least one public reference as exploit material. BlackTree has not independently validated that it is safe, reliable or weaponised.

Likely attack path
the affected interface → Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') → cause the confidentiality, integrity or availability impact described by the vendor
Attack surface
Unspecified
Privileges required
None: unauthenticated exploitation is possible

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-79 ↗

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'). The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.

?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.

Post-exploitation / living off the land
No specific living-off-the-land technique is confirmed in the structured sources. Monitor normal administration tools for activity inconsistent with the affected service's baseline.

Patch and workaround

Operational remediation based on structured source evidence.

Status
?Patch availability is based on structured fixed-version fields and authoritative update references. If no fix is verified, check the vendor advisory before making a change.
Patch available
Affected
n/a: n/a
Fixed
An authoritative update reference is available, but the fixed version is not recorded in the structured CVE fields. Check the linked vendor advisory for the applicable release.
Action
Review the linked authoritative reference and apply the recorded fixed release appropriate to the affected product branch.
Workaround
No verified workaround is recorded. Limit untrusted access and use least privilege until authoritative guidance is available.
