CVE-2014-6287 is a critical vulnerability that allows remote attackers to execute arbitrary programs on affected instances of Rejetto HTTP File Server (also known as HFS or HttpFileServer). This vulnerability arises from the findMacroMarker function in parserLib.pas, which fails to adequately handle a %00 sequence in a search action. The severity of this vulnerability is underscored by its CVSS score of 9.8, indicating critical risk.
Organizations utilizing Rejetto HTTP File Server versions 2.3x prior to 2.3c are at significant risk. Attackers may leverage this vulnerability to compromise system integrity, confidentiality, and availability, potentially leading to unauthorized access and control over server resources. It is imperative for organizations to prioritize this vulnerability in their patch management processes.
The vulnerability was publicly disclosed on October 7, 2014, and has been analyzed for its potential exploitation. As of the latest updates, it has been added to the Known Exploited Vulnerabilities (KEV) catalog, indicating its active exploitation in the wild.
Organizations should prioritize patching immediately to mitigate the risks associated with CVE-2014-6287. The urgency of this action cannot be overstated, as failure to address this vulnerability can lead to severe consequences, including data breaches and system compromises.
In summary, CVE-2014-6287 represents a critical vulnerability within the Rejetto HTTP File Server that necessitates immediate action from all users to ensure their systems remain secure.
Vulnerability Details
The findMacroMarker function in parserLib.pas in Rejetto HTTP File Server (HFS) version 2.3x prior to 2.3c is vulnerable to remote code execution. This vulnerability is classified under CWE-94, indicating improper control of generation of code ('Code Injection').
The CVSS score is 9.8, categorized as critical, with the following metrics: attack vector is network-based, attack complexity is low, no privileges are required, and user interaction is not necessary. The impacts on confidentiality, integrity, and availability are all rated high.
This vulnerability was published on October 7, 2014, and is documented in various advisory sources.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user input within the findMacroMarker function. Attackers can exploit this oversight by sending specially crafted requests that include the %00 sequence, leading to the execution of arbitrary commands.
The attack vector is network-based, meaning that an attacker does not need physical access to the system to exploit the vulnerability. The complexity of the attack is considered low, allowing attackers with minimal skills to potentially execute arbitrary code. No privileges are required for exploitation, and user interaction is not necessary.
Due to the critical impact on confidentiality, integrity, and availability, this vulnerability poses a significant threat to organizations running affected versions of Rejetto HTTP File Server.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2014-6287 is substantial, particularly for organizations that rely on Rejetto HTTP File Server for file sharing and web services. The potential blast radius is extensive, as successful exploitation could allow attackers to gain full control over the server, leading to data loss, service disruption, and reputational damage.
The urgency of addressing this vulnerability is highlighted by its critical CVSS score and inclusion in the KEV catalog, indicating ongoing exploitation in the wild. Organizations should assess their exposure to this vulnerability and prioritize remediation efforts.
