Information Disclosure Vulnerability in iTerm2 by Aernon Software

CVE-2025-22275

What is CVE-2025-22275?

CVE-2025-22275 is an information disclosure vulnerability identified in iTerm2, a popular terminal emulator for macOS developed by Aernon Software. iTerm2 facilitates improved command-line interface interactions, optimizing workflows for developers and system administrators. This vulnerability could negatively impact organizations by allowing remote attackers to access sensitive information through terminal commands, specifically by reading the /tmp/framer.txt file under certain SSH integration configurations. This risk is particularly significant for environments that utilize shared Python installations, exposing potentially confidential data to unauthorized users.

Technical Details

The vulnerability affects versions of iTerm2 from 3.5.6 to 3.5.10, which present a security gap when remote logins occur. Under specific conditions related to it2ssh and SSH integration, the application inadvertently permits attackers to glean sensitive information from the temporarily stored data in the framer.txt file. Affected organizations may find their security protocols weakened due to the ease of information retrieval by exploiting this flaw, making it essential to understand the operational context and configurations under which the vulnerability manifests.

Potential Impact of CVE-2025-22275

1. Data Exposure: Sensitive terminal command output, which may include authentication tokens, configuration information, or proprietary scripts, can be accessed by unauthorized parties, leading to potential data breaches.

2. Compromised System Integrity: If attackers leverage this vulnerability effectively, they may gain insights into the system’s security posture and operational structure, which could facilitate further attacks or exploitation of other vulnerabilities.

3. Increased Compliance Risk: Organizations that handle sensitive data may face compliance issues if they fail to address this vulnerability. Exposure of protected information could violate data protection regulations, potentially resulting in legal penalties and reputational damage.
