Evidence used

  • CISA confirms exploitation in the wild.
  • The selected CVSS metric records a network-reachable, unauthenticated path with no user interaction.
  • EPSS is 99.63% for the current model date.

Compensating controls

  • Apply the linked authoritative mitigation while planning the permanent fix.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Increase monitoring for the attack path and post-exploitation behaviour described in the report.

Verification

  1. Confirm that the asset runs ServiceNow Utah, Vancouver, and Washington DC Now Platform and falls inside the recorded affected range.
  2. Recheck the vendor advisory before scheduling a change because no verified fixed version is currently retained.
  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: Within 3 daysRemediation target: Within 90 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.

CISA KEV mirrored by ENISA

ServiceNow has addressed an input validation vulnerability that was identified in the Washington DC, Vancouver, and earlier Now Platform releases. This vulnerability could enable an unauthenticated user to remotely execute code within the context of the Now Platform. The vulnerability is addressed in the listed patches and hot fixes below, which were released during the June 2024 patching cycle. If you have not done so already, we recommend applying security patches relevant to your instance as soon as possible.

01

What, why and how

ServiceNow Washington DC, Vancouver, and earlier Now Platform releases contain an incomplete list of disallowed inputs vulnerability in the GlideExpression script. An unauthenticated user could exploit this vulnerability to execute code remotely.

What

ServiceNow Washington DC, Vancouver, and earlier Now Platform releases contain an incomplete list of disallowed inputs vulnerability in the GlideExpression script. An unauthenticated user could exploit this vulnerability to execute code remotely.

Why

The product implements a protection mechanism that relies on a list of inputs (or properties of inputs) that are not allowed by policy or otherwise require other action to neutralize before additional processing takes place, but the list is incomplete.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may execute code or commands in the affected security context.

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.
Confirmed in the wild

CISA added this CVE to its Known Exploited Vulnerabilities catalogue on 2024-07-29.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
a network path → Incomplete List of Disallowed Inputs → execute code or commands in the affected security context

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-184 ↗

CWE-184: Incomplete List of Disallowed Inputs. The product implements a protection mechanism that relies on a list of inputs (or properties of inputs) that are not allowed by policy or otherwise require other action to neutralize before additional processing takes place, but the list is incomplete.

Post-exploitation / living off the land
After compromise, an attacker may use built-in shells, scripting engines, scheduled tasks and native network utilities for discovery, persistence or movement. This is a plausible LoTL path, not evidence that it has occurred for every attack.
