Horizon Alert

Summary of the vulnerability and why it matters

A critical remote code execution vulnerability has been identified in the ESPCMS P8.21120101 system, specifically within its INPUT_ISDESCRIPTION component. This issue could allow unauthorized remote access and control over affected systems without requiring any user interaction or administrative privileges. The main concern is confirming relevance and exposure.

Allows remote takeover of systems.
Critical flaw, widely exploitable if present.
Confirm if your systems are affected.

Attack Path

How an attacker could exploit the issue

An attacker can remotely trigger a vulnerability within the INPUT_ISDESCRIPTION component of ESPCMS by exploiting its network accessibility. This vulnerability, once triggered, can lead to remote code execution, allowing an attacker to compromise the system. The attacker's journey likely involves identifying an exposed ESPCMS instance and interacting with the vulnerable component without needing any prior authentication or privileges.

Accessible over the network.
Exploits the INPUT_ISDESCRIPTION component.
Enables remote code execution.

Live Threat

Current exploitation, exposure, and threat context

A remote code execution vulnerability in the INPUT_ISDESCRIPTION component of ESPCMS could allow an unauthenticated attacker to execute arbitrary code on the server. This could occur when supported by the advisory's conditions, potentially impacting the integrity and availability of the affected system.

System code execution.
Via network with no authentication.
Compromise of system integrity and availability.

Operational Fix

Recommended remediation, mitigation, and detection steps

This critical remote code execution vulnerability in ESPCMS affects the INPUT_ISDESCRIPTION component. Application owners and platform teams should prioritize identifying all instances of ESPCMS. The first practical step is to locate affected systems, assess their exposure and business criticality, and then assign ownership for remediation planning.

Application owners should own the issue.
Verify external reachability and business criticality.
Plan remediation based on risk assessment.

Frequently asked questions

What is ESPCMS and what is it used for?

ESPCMS is a content management system (CMS) designed to help users build and manage websites. Because it serves as a platform for web content, it is typically deployed as a public-facing application, meaning its core functions are intended to be accessible to visitors over the internet.

What does CWE-94 mean in the context of CVE-2022-44088?

CVE-2022-44088 involves a weakness classified as CWE-94, or Improper Control of Generation of Code. In plain terms, this means the software incorrectly handles data provided to it, allowing an attacker to inject and execute their own unauthorized commands or instructions directly on the server hosting the application.

How is the INPUT_ISDESCRIPTION vulnerability triggered?

An attacker triggers this flaw by sending specifically crafted network requests to the vulnerable INPUT_ISDESCRIPTION component. Because the system does not require authentication or administrative privileges to process these requests, the bug can be triggered by anyone with network access to the application; it is not dependent on a user accidentally clicking a link or performing any other action.

Is my ESPCMS instance at risk?

If you run this software, you should consider it high risk. Halo Surface Signal notes that since ESPCMS is a web-based platform, its components—including the one affected here—are often exposed directly to the internet. Any instance reachable from the public web is a potential target for this remote code execution flaw.

What should I do if I use ESPCMS?

First, conduct an audit to identify every server running this specific version of ESPCMS. Once identified, evaluate which systems are exposed to the internet and assess their business importance. Assign clear ownership to these assets immediately so your team can develop a remediation plan to protect the server from unauthorized access.
