As a result, unintended operations to the device such as changes of the device settings may be conducted. The following multiple vulnerabilities exist in multiple products provided by Logitec Co., Ltd. -Inappropriate restriction of excessive authentication attempts (CWE-307) - CVE-2021-20635 ・ Cross-site request forgery (CWE-352) - CVE-2021-20636, CVE-2021-20641 • Improper checking or handling for exceptional situations (CWE-703) - CVE-2021-20637, CVE-2021-20642 ・ OS Command injection (CWE-78) - CVE-2021-20638 ・ OS Command injection (CWE-78) - CVE-2021-20639 ・ Buffer overflow (CWE-119) - CVE-2021-20640 CVE-2021-20635 This vulnerability information is based on the Information Security Early Warning Partnership. IPA Report to JPCERT/CC Coordinated with the developer. Reporter : Kanagawa Institute of Technology Minegishi Takaaki Mr. Okamoto Tsuyoshi Mr CVE-2021-20636, CVE-2021-20637, CVE-2021-20642 These vulnerability information is based on the Information Security Early Warning Partnership. IPA Report to JPCERT/CC Coordinated with the developer. Reporter : LAC Co., Ltd. Shuto Kono Mr CVE-2021-20638, CVE-2021-20639, CVE-2021-20640 These vulnerability information is based on the Information Security Early Warning Partnership. IPA Report to JPCERT/CC Coordinated with the developer. Reporter : Mitsui Bussan Secure Direction Co., Ltd. Tsukamoto Taizo Mr CVE-2021-20641 This vulnerability information is based on the Information Security Early Warning Partnership. IPA Report to JPCERT/CC Coordinated with the developer. Reporter : LAC Co., Ltd. Shuto Kono Mr. Techmatrix Corporation Atsuo Sakurai MrThe expected impact depends on each vulnerability, but it may be affected as follows. ・ Wireless of the corresponding device LAN By a third party within reach PIN Is decrypted and the network provided by the device is accessed. - CVE-2021-20635 ・ Of the product Web The user logged in to the admin page has been crafted URL You can unintentionally change the settings of the product by accessing - CVE-2021-20636, CVE-2021-20641 ・ Of the product Web The user logged in to the admin page has been crafted URL Interfering with service operations by accessing (DoS) Be attacked - CVE-2021-20637, CVE-2021-20642 ・ Of the product Web Arbitrary by an attacker with access to the admin page OS Command is executed - CVE-2021-20638, CVE-2021-20639, CVE-2021-20640. Logitec LAN-W300N/RS is vulnerable to cross-site request forgery, caused by improper validation of user-supplied input.
