CVE-2023-26207 describes an insertion of sensitive information into log file vulnerability in Fortinet FortiOS versions 7.2.0 through 7.2.4 and FortiProxy versions 7.0.0 through 7.0.10. This vulnerability allows an attacker to read certain passwords in plain text. The severity level assigned to this vulnerability is low, with a CVSS base score of 3.3, indicating that while the risk is present, it may not be immediately critical for most organizations.
The risk to organizations includes potential unauthorized access to sensitive information. With the ability to read passwords, attackers could leverage this information to escalate their privileges or gain further access within the network. Given the nature of the vulnerability, it is essential for organizations using affected versions to prioritize remediation efforts.
As of now, there are no known exploits publicly available for this vulnerability, and it has not been included in the Known Exploited Vulnerabilities (KEV) catalog. However, organizations should not underestimate the potential impact, as local access is sufficient for an attacker to exploit this vulnerability.
Organizations should address this vulnerability in their priority patch cycle. Immediate patching is recommended to prevent any exploitation attempts that may arise as the vulnerability becomes more widely known.
Vulnerability Details
The official description of CVE-2023-26207 states that it is an insertion of sensitive information into log files in Fortinet FortiOS and FortiProxy. The affected versions include FortiOS 7.2.0 through 7.2.4 and FortiProxy 7.0.0 through 7.0.10. The vulnerability is classified under CWE-532, which specifically addresses the logging of sensitive information.
The primary CVSS score is 6.5, denoting a medium severity level when considering the attack vector as network-based. The secondary score is lower at 3.3, reflecting the local attack vector context. The potential impacts on confidentiality are high, as attackers may gain access to sensitive passwords, while integrity and availability impacts are rated as none.
Technical Analysis
The root cause of this vulnerability lies in improper logging practices that allow sensitive information to be stored in plain text. The attack vector is local, requiring low privileges for exploitation, and no user interaction is necessary. Attack complexity is also low, making it feasible for attackers with basic skills to leverage this vulnerability.
The vulnerability's impact on confidentiality is significant, as sensitive passwords can be exposed, while integrity and availability remain unaffected. Organizations using the affected products must assess their logging configurations to prevent sensitive data from being written to log files.
Risk & Impact Analysis
Real-world deployment of Fortinet products places organizations at risk for this vulnerability if they are running the affected versions. The potential impact of this vulnerability extends beyond immediate exposure of passwords; it could facilitate further attacks if attackers gain footholds through compromised credentials.
The urgency for action is moderate, considering the low severity score. Organizations should schedule remediation as part of their regular maintenance routines, but they should remain vigilant for any signs of exploitation.

|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected versions for this vulnerability are Fortinet FortiOS 7.2.0 through 7.2.4 and FortiProxy 7.0.0 through 7.0.10. Organizations running these versions are strongly encouraged to apply necessary patches.
Mitigation & Remediation
Fortinet has released patches to address this vulnerability. Organizations should ensure they upgrade to the latest patched versions of FortiOS and FortiProxy. If immediate patching is not feasible, organizations may consider implementing logging configurations to sanitize sensitive information before it is written to log files.
To validate the effectiveness of remediation efforts, organizations should utilize penetration testing to ensure no sensitive data is being logged.
Detection Guidance
To monitor for potential exploitation, organizations should implement logging that flags any attempts to access sensitive log files. Additionally, monitoring for unusual access patterns or spikes in log file reads can help identify potential abuse.
AppSecure Threat Intelligence Insight
