CVE-2025-22275 is a critical vulnerability affecting iTerm2 versions 3.5.6 through 3.5.10, prior to version 3.5.11. This vulnerability allows remote attackers to obtain sensitive information from terminal commands by reading the /tmp/framer.txt file. This issue arises in specific it2ssh and SSH Integration configurations during remote logins to hosts with a shared Python installation.
The vulnerability has a CVSS score of 9.3, indicating a critical level of severity. The implications of this vulnerability are significant, as it can lead to unauthorized access to sensitive information, posing risks to organizations' data integrity and confidentiality.
Currently, there are no known exploits for this vulnerability, but organizations should not underestimate the potential for exploitation, given the critical nature of the issue. Organizations should prioritize patching this vulnerability immediately.
The urgency for defenders cannot be overstated, as failure to address this vulnerability can lead to significant security breaches.
Vulnerability Details
The official description of CVE-2025-22275 states that iTerm2 versions 3.5.6 to 3.5.10 sometimes allow remote attackers to obtain sensitive information from terminal commands by reading the /tmp/framer.txt file. The vulnerability is classified under CWE-532, indicating the risk of information exposure.
According to the CVSS 3.1 vector, the attack vector is NETWORK, the attack complexity is LOW, and no privileges are required for exploitation. There is no user interaction necessary to trigger this vulnerability, and the scope is classified as CHANGED, meaning that the impact can affect other components.
The confidentiality impact is rated as HIGH, while integrity impact is LOW, and there is no availability impact. This indicates that while the attacker can access sensitive information, they cannot alter data or disrupt service.
Technical Analysis
The root cause of this vulnerability lies in the insecure handling of terminal command outputs and sensitive files. The attack vector is primarily through remote access, where attackers can exploit configurations that allow them to read from the /tmp directory.
The attack complexity is low as it does not require any special conditions or high-level skills from the attacker. The vulnerability necessitates no privileges, meaning any remote attacker can exploit it without authentication.
User interaction is also not required, making it easier for attackers to leverage this vulnerability. The potential for confidentiality impact is significant due to the nature of the information that can be accessed through this vulnerability.
Risk & Impact Analysis
Organizations deploying iTerm2 versions 3.5.6 to 3.5.10 face substantial risks due to this vulnerability. The ability for remote attackers to read sensitive command outputs poses a real threat, particularly if these commands contain sensitive information such as passwords or personal data.
The blast radius of this vulnerability could extend beyond merely the affected systems, impacting organizational reputation and customer trust if sensitive data is compromised. Given the critical CVSS score of 9.3, organizations should prioritize remediation efforts, integrating patching into their security protocols immediately.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected versions of iTerm2 are 3.5.6 through 3.5.10. Organizations should ensure they are using version 3.5.11 or later to mitigate this vulnerability.
Mitigation & Remediation
Organizations must patch their iTerm2 installations to version 3.5.11 or later to remediate this vulnerability. If immediate patching is not feasible, consider implementing network controls to limit access to the affected systems and monitor for any unauthorized access attempts.
For ongoing security, organizations should adopt a comprehensive security testing approach, including regular penetration testing and assessments to identify potential vulnerabilities.
Penetration testing can help validate the effectiveness of remediation efforts.
Detection Guidance
Organizations should monitor logs for any attempts to access the /tmp/framer.txt file, which may indicate an attack. Additionally, behavioral anomalies during SSH sessions should be investigated to detect potential exploitation attempts.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2025-22275 highlights the ongoing risks associated with remote access tools and their configurations. Security teams must prioritize secure configurations and regular updates to mitigate these risks.
This vulnerability serves as a reminder of the importance of thorough testing and validation of security measures, especially in environments where sensitive information is handled.
A vulnerability management program should be established to continuously monitor for emerging threats and vulnerabilities.
Penetration testing methodology can aid in identifying and mitigating vulnerabilities before they can be exploited.
API penetration testing is also crucial for ensuring that all interfaces are secure and not susceptible to similar vulnerabilities.
