CVE-2023-6199 affects Book Stack version 23.10.2, which allows filtering local files on the server due to an SSRF vulnerability. This weakens the application's security posture, thereby exposing sensitive information. The CVSS score of 6.5 categorizes this vulnerability as medium severity, indicating a significant potential impact on confidentiality should it be exploited.
Risk to organizations includes potential unauthorized access to sensitive files, which could lead to data breaches. Given the low attack complexity and low privilege requirements, this vulnerability presents a real threat that should be addressed promptly. Organizations should prioritize patching immediately.
As of now, there are no confirmed public exploits for CVE-2023-6199, but its existence in GitHub repositories indicates that its potential exploitation is feasible. Organizations utilizing Book Stack should schedule remediation as part of their priority patch cycle.
In summary, organizations using Book Stack version 23.10.2 must address this vulnerability to mitigate risks associated with local file exposure. Immediate action is advised to secure their applications.
Vulnerability Details
The official description of CVE-2023-6199 states that it allows filtering of local files on the server due to a vulnerability in Book Stack version 23.10.2. This vulnerability falls under the Common Weakness Enumeration (CWE-918) category, indicating a server-side request forgery (SSRF) issue.
The CVSS score of 6.5 indicates a medium severity level, suggesting that while the vulnerability is serious, it is not the highest priority for patching. The attack vector is classified as network-based, with low complexity and low privilege requirements necessary for exploitation.
Published on November 20, 2023, this vulnerability has implications for any organization using the affected version of Book Stack. The lack of integrity and availability impact further emphasizes the focus on confidentiality risk.
Technical Analysis
The root cause of this vulnerability is the application’s failure to properly validate user input in requests that allow local file access. This oversight enables attackers to manipulate requests to access sensitive files on the server.
The attack vector is classified as network-based, meaning that an attacker can exploit this vulnerability remotely without physical access to the server. The attack complexity is rated as low, indicating that minimal skill is required to execute an attack. Privileges required are also low, meaning that an attacker does not need elevated permissions to exploit this vulnerability.
User interaction is not required, making the attack easier to execute. The vulnerability has a high confidentiality impact, meaning that successful exploitation could lead to unauthorized access to sensitive data, while there is no impact on integrity or availability.
Risk & Impact Analysis
Organizations deploying Book Stack version 23.10.2 face significant risks due to this vulnerability. The possibility of unauthorized access to sensitive files poses a direct threat to data confidentiality. Given the ease of exploitation, the potential blast radius is considerable, especially for organizations handling sensitive information.
As this vulnerability is categorized as a medium severity issue, organizations should address it in their priority patch cycle. The high confidentiality impact raises concerns about data exposure, making it imperative for organizations to take immediate action to mitigate risks.
Organizations must recognize the urgency of remediating this vulnerability to safeguard against potential data breaches. Regular vulnerability assessments and penetration testing can help identify and mitigate such vulnerabilities before they are exploited.
