CVE-2018-15439 – Cisco Small Business Switches Privileged Access Vulnerability
https://notcve.org/view.php?id=CVE-2018-15439
A vulnerability in the Cisco Small Business Switches software could allow an unauthenticated, remote attacker to bypass the user authentication mechanism of an affected device. The vulnerability exists because under specific circumstances, the affected software enables a privileged user account without notifying administrators of the system. An attacker could exploit this vulnerability by using this account to log in to an affected device and execute commands with full admin rights. Cisco has not released software updates that address this vulnerability. This advisory will be updated with fixed software information once fixed software becomes available. • http://www.securityfocus.com/bid/105873 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20181107-sbsw-privacc • CWE-798: Use of Hard-coded Credentials •
CVE-2018-0209
https://notcve.org/view.php?id=CVE-2018-0209
A vulnerability in the Simple Network Management Protocol (SNMP) subsystem communication channel through the Cisco 550X Series Stackable Managed Switches could allow an authenticated, remote attacker to cause the device to reload unexpectedly, causing a denial of service (DoS) condition. The device nay need to be manually reloaded to recover. The vulnerability is due to lack of proper input throttling of ingress SNMP traffic over an internal interface. An attacker could exploit this vulnerability by sending a crafted, heavy stream of SNMP traffic to the targeted device. An exploit could allow the attacker to cause the device to reload unexpectedly, causing a DoS condition. • http://www.securityfocus.com/bid/103406 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180307-550x • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2017-12308
https://notcve.org/view.php?id=CVE-2017-12308
A vulnerability in the web framework of Cisco Small Business Managed Switches software could allow an unauthenticated, remote attacker to conduct an HTTP response splitting attack against a user of the web interface of an affected system. The vulnerability is due to insufficient input validation of some parameters that are passed to the web server of the affected system. An attacker could exploit this vulnerability by convincing a user to follow a malicious link or by intercepting a user request and injecting malicious code into the request. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected web interface or allow the attacker to access sensitive browser-based information. This vulnerability affects the following Cisco Small Business 300 and 500 Series Managed Switches: Cisco 350 Series Managed Switches, Cisco 350X Series Stackable Managed Switches, Cisco 550X Series Stackable Managed Switches, Cisco ESW2 Series Advanced Switches, Cisco Small Business 300 Series Managed Switches, Cisco Small Business 500 Series Stackable Managed Switches. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180117-300-500-smb2 • CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting') •
CVE-2017-12307
https://notcve.org/view.php?id=CVE-2017-12307
A vulnerability in the web framework of Cisco Small Business Managed Switches software could allow an unauthenticated, remote attacker to conduct a reflected cross-site scripting (XSS) attack against a user of the web interface of an affected system. The vulnerability is due to insufficient input validation of parameters that are passed to the web server of the affected system. An attacker could exploit this vulnerability by convincing a user to follow a malicious link or by intercepting and injecting code into a user request. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected web interface or allow the attacker to access sensitive browser-based information. This vulnerability affects the following Cisco Small Business 300 and 500 Series Managed Switches: Cisco Small Business 300 Series Managed Switches, Cisco Small Business 500 Series Stackable Managed Switches, Cisco 350 Series Managed Switches, Cisco 350X Series Stackable Managed Switches, Cisco 550X Series Stackable Managed Switches, Cisco ESW2 Series Advanced Switches. • http://www.securityfocus.com/bid/102718 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20180117-300-500-smb1 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVE-2017-6720
https://notcve.org/view.php?id=CVE-2017-6720
A vulnerability in the Secure Shell (SSH) subsystem of Cisco Small Business Managed Switches software could allow an authenticated, remote attacker to cause a reload of the affected switch, resulting in a denial of service (DoS) condition. The vulnerability is due to improper processing of SSH connections. An attacker could exploit this vulnerability by logging in to an affected switch via SSH and sending a malicious SSH message. This vulnerability affects the following Cisco products when SSH is enabled: Small Business 300 Series Managed Switches, Small Business 500 Series Stackable Managed Switches, 350 Series Managed Switches, 350X Series Stackable Managed Switches, 550X Series Stackable Managed Switches, ESW2 Series Advanced Switches.
