A vulnerability classified as problematic has been found in TP-Link TL-SG108E 1.0.0 Build 20201208 Rel. 40304. This vulnerability allows manipulation of the argument username/password, leading to the use of GET request methods with sensitive query strings. Although the complexity of an attack is rather high, it is possible to exploit this vulnerability remotely.
The exploitability is considered difficult, and while no public exploit has been confirmed, the vulnerability has been disclosed. Organizations using this firmware version should prioritize addressing this vulnerability to prevent potential sensitive data exposure.
Upgrading to version 1.0.0 Build 20250124 Rel. 54920(Beta) is recommended to mitigate this issue. The vendor was contacted early, and they provided a pre-fix version for their customers. Organizations should prioritize patching immediately.
This vulnerability is particularly concerning due to its potential to expose sensitive information and the difficulty associated with its exploitation. Security teams are encouraged to monitor their environments for any indications of attempts to exploit this vulnerability.
Vulnerability Details
The vulnerability is found in the file /usr_account_set.cgi of the HTTP GET Request Handler component. It is classified under CWE-598, indicating an exposure of sensitive information through a data query. The CVSS score is 6.3, classifying it as medium severity, primarily due to its network attack vector and high attack complexity.
The vulnerability affects TP-Link TL-SG108E firmware version 1.0.0 Build 20201208 Rel. 40304. Organizations should ensure they upgrade to the patched version to mitigate risks.
Technical Analysis
The root cause of this vulnerability lies in the insecure handling of sensitive query strings in GET requests. The attack vector is network-based, requiring no privileges or user interaction, making it accessible to any attacker with network access.
The attack complexity is rated as high due to the need for crafted requests that correctly manipulate the relevant parameters. While the confidentiality impact of this vulnerability is low, the potential for sensitive data exposure remains a concern.
The information that could be exposed through successful exploitation includes sensitive account information, which could lead to further attacks if not properly mitigated.
Risk & Impact Analysis
The real-world risk of this vulnerability primarily affects organizations that utilize the affected TP-Link TL-SG108E firmware. Given the complexity of the attack, while it may not be trivial to execute, the potential for sensitive data exposure necessitates immediate attention.
Organizations should assess their network security posture and prioritize patching this vulnerability to minimize the risk of data breaches and unauthorized access. The urgency of addressing this vulnerability is medium, considering the exploitability and potential impacts.
The blast radius of this vulnerability is significant, as successful exploitation could lead to unauthorized access to sensitive information. Therefore, organizations must remain vigilant and proactive in their security measures.
