CWE-79Published: May 3, 2024· Updated: Jun 17, 2026

9.6

CVSS v3.1

Official Description

Softing edgeAggregator Client Cross-Site Scripting Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Softing edgeAggregator. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the handling of the input parameters provided to the edgeAggregetor client. The issue results from the lack of proper validation of user-supplied data, which can lead to the injection of an arbitrary script. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root. Was ZDI-CAN-20504.

Risk Analysis

Softing edgeAggregator and Secure Integration Server are vulnerable to cross-site scripting that can be leveraged for remote code execution as root. The flaw requires user interaction and has a CVSS score of 9.6, making it a critical risk.

No public exploit is known, and it is not in the CISA KEV. The vulnerability is remotely exploitable but requires user interaction.

Recommended Action

Upgrade to the latest version of the affected Softing software. Users should avoid interacting with untrusted content while using the software interface.

Technical Analysis

CVE-2023-27335 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.6.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.

From a weakness classification perspective (CWE-79): Cross-site scripting (XSS) vulnerabilities allow attackers to inject malicious scripts into web pages viewed by other users.
