CVE-2025-0728 is a medium-severity vulnerability affecting the NetX HTTP server functionality of Eclipse ThreadX NetX Duo before version 6.4.2. This vulnerability allows attackers to cause an integer underflow and a subsequent denial of service by sending specially crafted packets with a Content-Length smaller than the data request size. The potential impact includes service disruption, making it critical for organizations using this software to take action.
The CVSS score for this vulnerability is 5.3, indicating a medium severity level. The risk to organizations includes denial of service, which could affect the availability of the service. It is essential for organizations to address this vulnerability as part of their security posture.
Currently, there are no known exploits or public proof-of-concept code associated with CVE-2025-0728. However, organizations should remain vigilant as the situation may evolve. Immediate patching is recommended to prevent potential exploitation, even in the absence of active threats.
Organizations should prioritize patching immediately. A potential workaround is to disable HTTP PUT support until a patch is applied.
Vulnerability Details
The vulnerability description states: "In NetX HTTP server functionality of Eclipse ThreadX NetX Duo before version 6.4.2, an attacker can cause an integer underflow and a subsequent denial of service by writing a very large file, by specially crafted packets with Content-Length smaller than the data request size. A possible workaround is to disable HTTP PUT support." The CWE classification for this vulnerability is CWE-191, which indicates an integer underflow.
According to the CVSS 3.1 metrics, the vulnerability has a base score of 7.5, categorizing it as high severity. The attack vector is network-based, with low attack complexity, meaning that no special conditions are required to exploit this vulnerability. No user interaction is required, and the attacker only needs low privileges.
Technical Analysis
The root cause of CVE-2025-0728 stems from insufficient validation of the Content-Length header in HTTP requests, which can be manipulated by an attacker. This manipulation can lead to an integer underflow, ultimately resulting in a denial of service. The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely.
The attack complexity is low, as the attacker does not need special conditions or high privileges to exploit this vulnerability. User interaction is not required, further simplifying the exploitation process. The availability impact is rated as low, indicating that the service may become temporarily unavailable following an attack.
Risk & Impact Analysis
The deployment of Eclipse ThreadX NetX Duo in critical infrastructure could pose significant risks if this vulnerability is not addressed. The potential denial of service can disrupt operations, leading to financial losses and reputational damage. Organizations should assess their exposure to this vulnerability and prioritize mitigation measures.
Given the CVSS score of 7.5, organizations should address this vulnerability in their priority patch cycle. The lack of known exploits does not diminish the urgency to remediate, as unpatched vulnerabilities can lead to unforeseen exploitation methods.
Exploitation Status
