A vulnerability, which was classified as critical, has been found in D-Link DAP-1320 1.00. Affected by this issue is the function replace_special_char of the file /storagein.pd-XXXXXX. The manipulation leads to stack-based buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. This vulnerability only affects products that are no longer supported by the maintainer.
With a CVSS score of 8.7, this vulnerability poses a significant risk to organizations, particularly as it can be exploited remotely with low attack complexity and low privileges required. Organizations should prioritize patching immediately.
Risk to organizations includes unauthorized access to sensitive information and potential system compromise. As this vulnerability is actively being exploited, swift action is necessary to mitigate the risks associated with it.
Defenders should be aware that this vulnerability affects devices no longer supported by D-Link, increasing the urgency for organizations to replace outdated systems to avoid exploitation.
Vulnerability Details
The vulnerability in question allows for a stack-based buffer overflow due to improper handling of special characters within the affected D-Link DAP-1320 firmware. This issue is classified under multiple CWE identifiers, including CWE-119 and CWE-787, indicating serious flaws in how data is managed within memory.
The CVSS score of 8.7 signifies a high severity level, highlighting the need for immediate attention. The vulnerability was published on February 21, 2025, and has been analyzed extensively since.
Given the nature of this vulnerability, organizations should assess their current use of D-Link DAP-1320 devices and consider the implications of running unsupported firmware.
Technical Analysis
The root cause of this vulnerability lies in the improper validation of input data, where special characters are not adequately managed within the replace_special_char function. Attackers may exploit this flaw by sending crafted input that triggers a buffer overflow, leading to arbitrary code execution.
The attack vector is network-based, allowing exploitation from remote locations without requiring physical access to the device. The complexity of the attack is low, meaning that even attackers with minimal skills can exploit this vulnerability.
Privileges required for exploitation are low, and no user interaction is needed, making this vulnerability particularly dangerous. The potential impacts include high confidentiality, integrity, and availability risks, as successful exploitation could lead to complete system control.
Risk & Impact Analysis
Organizations using D-Link DAP-1320 devices face substantial risks due to the remote exploitability of this vulnerability. The implications of such an exploitation include unauthorized access to sensitive data, disruption of service, and potential for further attacks within the network.
Given the high CVSS score and the nature of the vulnerability, organizations should assess their exposure risk and prioritize remediation efforts. With this vulnerability classified as high severity, immediate action is recommended to prevent potential exploits.
The blast radius of this vulnerability can extend to all devices running the affected firmware, emphasizing the urgency for organizations to take proactive measures to safeguard their systems.
