## Description

A code injection vulnerability in Ivanti Endpoint Manager Mobile (EPMM) allows unauthenticated remote attackers to execute arbitrary code on affected on-premises installations via the Android File Transfer Configuration feature.

## CrowdSec analysis

[CVE-2026-1340](https://euvd.enisa.europa.eu/vulnerability/CVE-2026-1340) is a critical code injection vulnerability in Ivanti Endpoint Manager Mobile (EPMM). The flaw exists in a Bash script that processes HTTP requests to the `/mifs/c/aftstore/fob/` endpoint, which services the Android File Transfer Configuration feature. Due to improper sanitization of user input during Bash arithmetic expansion, unauthenticated attackers can inject OS commands via crafted URL parameters that get executed when the shell evaluates array index expressions. Successful exploitation grants full control over the EPMM appliance, potentially exposing sensitive MDM data including user PII, device identifiers, and GPS locations.

CrowdSec has been tracking this vulnerability and its exploits since 2nd of February 2026.

Data from the CrowdSec community indicates that exploitation of CVE-2026-1340 is highly selective and intelligence-driven. Threat actors use advanced reconnaissance and carefully choose their targets, often as part of sophisticated campaigns or advanced persistent threat operations.
Data from the CrowdSec community also indicates a gradual decrease in attacks targeting CVE-2026-1340. While still present in the wild, exploitation levels have dropped noticeably week-over-week. This may signal that the vulnerability is becoming less relevant or that defenses are improving fast enough for attackers to lose interest.

Exploitation attempts target URLs matching `/mifs/c/aftstore/fob/` containing code injection payloads. The vulnerable Bash script processes user-controlled input in a similar manner to CVE-2026-1281, where Bash arithmetic expansion can be abused to achieve command execution. Malicious requests typically include URL-encoded backticks (`%60`), square brackets (`%5B`, `%5D`), or Bash variable references within the URL parameters.
