# Ivanti CSA auth bypass and RCE flaws disclosed

Canonical: https://vorant.io/reports/103f1766-f344-5cac-bb24-c7f8d348a8b6/ivanti-csa-auth-bypass-and-rce-flaws-disclosed

> Three unauthenticated-to-RCE vulnerabilities in Ivanti Cloud Services Application 5.0.2 and prior; no active exploitation reported.

Ivanti has disclosed three vulnerabilities in Cloud Services Application (CSA) versions 5.0.2 and prior. The most critical is CVE-2024-11639, an authentication bypass in the admin web console that allows unauthenticated remote attackers to gain administrative access. Combined with CVE-2024-11772, a command injection flaw requiring admin privileges, attackers can achieve remote code execution. A third vulnerability, CVE-2024-11773, allows SQL injection in the admin console. Successful RCE exploitation permits installation of programs, data viewing, modification, or deletion depending on system privilege context.

No active exploitation in the wild has been reported at the time of disclosure. Ivanti has released version 5.0.3 to address these issues. The advisory recommends immediate patching, implementation of least-privilege access controls, network segmentation, and vulnerability scanning to detect exploitable instances. Organizations running CSA should treat authentication bypass plus RCE chain as urgent remediation priority.

## Mentioned in this report

- Vulnerabilities: CVE-2024-11639, CVE-2024-11772, CVE-2024-11773

## Detection guidance (public sample)

### Linux Web Server Process Spawning Shell With Download or Recon Commands

ATT&CK: T1190

Web server or PHP worker spawning a shell that runs download, reverse-shell or recon commands, consistent with command injection RCE in a public-facing admin console such as an Ivanti CSA exploit chain. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.

title: Linux Web Server Process Spawning Shell With Download or Recon Commands
id: 1e5295cb-3df8-59ee-ba4b-73f95e0eb8bf
status: experimental
description: Detects a web server or PHP process (apache2, httpd, php-fpm, nginx)
  spawning a shell whose command line contains download, reverse-shell or recon commands.
  Behaviour expected after command injection in a web admin console (for example CVE-2024-11772
  chained with the CVE-2024-11639 auth bypass on Ivanti CSA). Generalises on the parent/child
  relation, not on specific URIs or payloads.

### SQL Injection Patterns in Web Admin Console Request Query

ATT&CK: T1190

Web server requests whose query string contains common SQL injection constructs, relevant to SQL injection in public-facing admin consoles such as CVE-2024-11773. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.

```yaml
title: SQL Injection Patterns in Web Admin Console Request Query
id: 3bfbaf7f-e6ed-5f43-864d-45404f0e60ae
status: experimental
description: Detects SQL injection constructs (UNION SELECT, time-based sleep, information_schema
  access, boolean tautologies) in the request query string of web server logs. Relevant
  to SQL injection in public-facing admin consoles such as Ivanti CSA CVE-2024-11773.
  Tune to the CSA host or admin console virtual host and review volume before alerting
  broadly.
