CVE-2025-22997 is a medium-severity stored cross-site scripting (XSS) vulnerability that affects the prf_table_content component of Linksys E5600 Router, specifically version 1.1.0.26. This vulnerability allows attackers to execute arbitrary web scripts or HTML by injecting a crafted payload into the desc parameter. The CVSS score for this vulnerability is 4.8, indicating a medium risk level that should not be overlooked. Organizations using this router model must be aware of this vulnerability as it poses a tangible risk to their network security.
The potential risk to organizations includes unauthorized access to sensitive information or system control due to the ability to execute arbitrary scripts. The vulnerability's exploitation is feasible within an adjacent network, where an attacker, possessing low privileges and requiring user interaction, can take advantage of the flaw. Given the nature of the attack vector and the resultant impacts on confidentiality and integrity, organizations should prioritize patching immediately.
Currently, there are no known public exploits confirmed for CVE-2025-22997, which may provide a temporary window for remediation. Nonetheless, organizations should not delay, as the threat landscape can evolve rapidly. Regular updates and vigilance against emerging threats are essential for securing networked devices such as routers.
For affected organizations, it is crucial to assess the deployment of the Linksys E5600 Router and implement necessary mitigations, including patching to the latest firmware version. Security teams are urged to incorporate this vulnerability into their risk management strategies and remediation plans.
Vulnerability Details
The CVE description indicates that this stored XSS vulnerability allows attackers to execute arbitrary web scripts or HTML through crafted payloads injected into the desc parameter of the prf_table_content component of the Linksys E5600 Router, version 1.1.0.26. The vulnerability is classified under CWE-79.
The CVSS score is 4.8, categorized as medium severity. The attack vector is classified as adjacent network, and the attack complexity is low. The attacker requires low privileges, and user interaction is necessary. The impact on confidentiality and integrity is low, while availability is unaffected.
Technical Analysis
The root cause of CVE-2025-22997 lies in improper handling of user input within the affected component. The vulnerability arises because the system does not adequately sanitize the input, allowing an attacker to inject malicious scripts. This can lead to the execution of arbitrary code in the context of the victim's browser, effectively compromising user data and interaction with the application.
The attack vector for this vulnerability is adjacent network, which means that an attacker needs to be on the same local network as the target device. Given the low attack complexity, this vulnerability can be exploited with minimal effort. The attacker requires low privileges and must rely on user interaction to execute the malicious payload.
While the confidentiality and integrity impacts are classified as low, the potential for exploitation exists, making it crucial for organizations to take proactive measures. The availability impact for this vulnerability is non-existent, meaning that service disruption is not a direct consequence of exploitation.
Risk & Impact Analysis
Organizations deploying the Linksys E5600 Router version 1.1.0.26 should evaluate the risk associated with CVE-2025-22997. The stored XSS vulnerability presents a significant risk as it allows attackers to execute arbitrary scripts within the context of the user's browser session. This could lead to unauthorized data access and manipulation.
The urgency for remediation is highlighted by the nature of the attack vector, which is accessible to any attacker within the adjacent network. Given the medium CVSS score, organizations should address this vulnerability in their priority patch cycle to mitigate the risks effectively.
The blast radius of this vulnerability is potentially widespread within organizations that utilize the affected router model. Without timely remediation, the risk of exploitation increases, as attackers may leverage this vulnerability to gain unauthorized access to sensitive information.
