CVE-2024-5585 is a high-severity vulnerability affecting PHP versions 8.1.* before 8.1.29, 8.2.* before 8.2.20, and 8.3.* before 8.3.8. This vulnerability allows attackers to exploit the proc_open() command due to insufficient escaping in argument handling. The original issue relates to the handling of command names that include trailing spaces, which can lead to the execution of arbitrary commands in the Windows shell.
With a CVSS score of 7.7, this vulnerability poses a significant risk to organizations using the affected PHP versions. Attackers may leverage this flaw to execute commands that could compromise the integrity and confidentiality of the system. Organizations should prioritize patching immediately.
Although there are no public exploits confirmed at this time, the potential for exploitation exists due to the high exploitability score. It is crucial for organizations to assess their environments and apply the necessary patches to mitigate this vulnerability effectively.
The urgency for remediation is high, considering the potential impact on systems running vulnerable PHP versions. Failure to address this vulnerability could lead to severe consequences, including unauthorized access and data breaches.
Vulnerability Details
The vulnerability description states that in PHP versions 8.1.* before 8.1.29, 8.2.* before 8.2.20, and 8.3.* before 8.3.8, the fix for CVE-2024-1874 does not work properly if the command name includes trailing spaces. This issue arises when using proc_open() with array syntax, allowing a malicious user to control the command arguments and execute arbitrary commands.
The vulnerability has a CVSS score of 7.7, indicating a high severity level and highlighting the importance of immediate action. The affected products include PHP and Fedora, with the vulnerability disclosed on June 9, 2024.
Technical Analysis
The root cause of CVE-2024-5585 stems from insufficient escaping when handling command arguments in proc_open(). This vulnerability has a high attack complexity, meaning that an attacker must have detailed knowledge of the system and the command structure used.
The attack vector is network-based, requiring no privileges and no user interaction, making it easier for an attacker to exploit. The attack could potentially impact confidentiality and integrity significantly while having a lower impact on availability.
Risk & Impact Analysis
The real-world risk associated with CVE-2024-5585 is substantial, especially in environments where PHP is extensively used for web applications or services. Attackers exploiting this vulnerability can execute arbitrary commands, leading to potential data loss, unauthorized access, and system compromise.
Organizations utilizing affected PHP versions must act swiftly to patch their systems. The blast radius for this vulnerability is significant, given the widespread use of PHP across various platforms. Immediate action is necessary to minimize potential damage and protect sensitive data.
The urgency assessment based on the CVSS score categorizes this vulnerability as requiring high priority remediation. Organizations should address this as part of their ongoing security management practices.
