Technical Analysis

CVE-2025-44879 is a high-severity buffer overflow vulnerability identified in the WS-WN572HP3 device, specifically in the /www/cgi-bin/upload.cgi component. This vulnerability arises from improper handling of input data in the upload.cgi script, which processes HTTP requests. An attacker can exploit this flaw by sending a specially crafted HTTP request designed to overflow the buffer, causing the device to crash or become unresponsive, resulting in a Denial of Service (DoS) condition. The vulnerability is classified under CWE-120, which pertains to classic buffer overflow issues where input data exceeds the allocated buffer size, leading to memory corruption. According to the CVSS v3.1 scoring, this vulnerability has a score of 7.5, indicating high severity. The vector metrics show that the attack can be performed remotely over the network (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and affects the availability of the system (A:H) without impacting confidentiality or integrity. No known exploits are currently reported in the wild, and no patches or vendor advisories are available at this time. The vulnerability was published on May 14, 2025, with the initial reservation date on April 22, 2025. The affected product is a network device model WS-WN572HP3, which likely serves as a wireless access point or similar network infrastructure component, given the naming convention. The vulnerability's exploitation could disrupt network availability by causing device crashes, impacting connected users and dependent services.

Potential Impact

For European organizations, the impact of CVE-2025-44879 could be significant, especially for those relying on the WS-WN572HP3 device or similar network infrastructure in critical environments. A successful exploitation would lead to denial of service, potentially disrupting network connectivity, access to internal resources, and internet access for users. This could affect business continuity, especially in sectors requiring high availability such as finance, healthcare, manufacturing, and public services. The lack of confidentiality and integrity impact reduces the risk of data breaches or unauthorized data modification; however, the availability disruption alone can cause operational delays, loss of productivity, and reputational damage. Organizations with remote or distributed workforces relying on stable wireless connectivity could experience increased downtime. Additionally, if these devices are part of a larger network infrastructure, the DoS could cascade, affecting multiple network segments. Since no authentication or user interaction is required for exploitation, attackers can launch attacks remotely and at scale, increasing the threat surface. The absence of known exploits in the wild currently limits immediate risk but does not preclude future exploitation attempts.

Mitigation Recommendations

Given the absence of official patches or vendor advisories, European organizations should implement the following specific mitigations: 1) Identify and inventory all WS-WN572HP3 devices within the network to assess exposure. 2) Restrict access to the device management interfaces, especially the /www/cgi-bin/upload.cgi endpoint, by implementing network segmentation and firewall rules that limit HTTP access to trusted management networks or IP addresses only. 3) Employ intrusion detection/prevention systems (IDS/IPS) with custom signatures to detect and block anomalous HTTP requests targeting the upload.cgi script, particularly those with unusual payload sizes or malformed data. 4) Monitor device logs and network traffic for signs of repeated or suspicious HTTP requests that could indicate exploitation attempts. 5) Consider temporary removal or replacement of vulnerable devices in critical environments until a patch or firmware update is available. 6) Engage with the device vendor or manufacturer for updates or security advisories and subscribe to vulnerability notification services for timely patch releases. 7) Implement network redundancy and failover mechanisms to minimize impact in case of device failure due to exploitation. 8) Educate network administrators about this vulnerability and ensure strict configuration management to avoid exposure.
