CVSS: 6.0EPSS: 0%CPEs: 1917EXPL: 0CVE-2020-3201 – Cisco IOS and IOS XE Software Tcl Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3201
A vulnerability in the Tool Command Language (Tcl) interpreter of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, local attacker with privileged EXEC credentials to cause a denial of service (DoS) condition on an affected system. The vulnerability is due to insufficient input validation of data passed to the Tcl interpreter. An attacker could exploit this vulnerability by executing crafted Tcl arguments on an affected device. An exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition. Una vulnerabilidad en el intérprete Tool Command Language (Tcl) de Cisco IOS Software y Cisco IOS XE Software, podría permitir a un atacante local autenticado con credenciales EXEC privilegiadas causar una condición de denegación de servicio (DoS) en un sistema afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-tcl-dos-MAZQUnMF • CWE-20: Improper Input Validation •
CVSS: 8.4EPSS: 0%CPEs: 34EXPL: 0CVE-2019-1950 – Cisco IOS XE SD-WAN Software Default Credentials Vulnerability
https://notcve.org/view.php?id=CVE-2019-1950
A vulnerability in Cisco IOS XE SD-WAN Software could allow an unauthenticated, local attacker to gain unauthorized access to an affected device. The vulnerability is due to the existence of default credentials within the default configuration of an affected device. An attacker who has access to an affected device could log in with elevated privileges. A successful exploit could allow the attacker to take complete control of the device. This vulnerability affects Cisco devices that are running Cisco IOS XE SD-WAN Software releases 16.11 and earlier. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-sd-wan-cred-EVGSF259 • CWE-255: Credentials Management Errors CWE-1188: Initialization of a Resource with an Insecure Default •
CVSS: 4.8EPSS: 0%CPEs: 22EXPL: 0CVE-2019-12668 – Cisco IOS and IOS XE Software Stored Banner Cross-Site Scripting Vulnerability
https://notcve.org/view.php?id=CVE-2019-12668
A vulnerability in the web framework code of Cisco IOS and Cisco IOS XE Software could allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the web interface of the affected software using the banner parameter. The vulnerability is due to insufficient input validation of the banner parameters that are passed to the web server of the affected software. An attacker could exploit this vulnerability by crafting a banner parameter and saving it. The attacker could then convince a user of the web interface to access a malicious link or could intercept a user request for the affected web interface and inject 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. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-sbxss • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2019-12660 – Cisco IOS XE Software ASIC Register Write Vulnerability
https://notcve.org/view.php?id=CVE-2019-12660
A vulnerability in the CLI of Cisco IOS XE Software could allow an authenticated, local attacker to write values to the underlying memory of an affected device. The vulnerability is due to improper input validation and authorization of specific commands that a user can execute within the CLI. An attacker could exploit this vulnerability by authenticating to an affected device and issuing a specific set of commands. A successful exploit could allow the attacker to modify the configuration of the device to cause it to be non-secure and abnormally functioning. Una vulnerabilidad en la CLI del Software Cisco IOS XE, podría permitir a un atacante local autenticado escribir valores en la memoria subyacente de un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-awr • CWE-668: Exposure of Resource to Wrong Sphere •
CVSS: 8.6EPSS: 0%CPEs: 19EXPL: 0CVE-2019-12654 – Cisco IOS and IOS XE Software Session Initiation Protocol Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-12654
A vulnerability in the common Session Initiation Protocol (SIP) library of Cisco IOS and IOS XE Software could allow an unauthenticated, remote attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient sanity checks on an internal data structure. An attacker could exploit this vulnerability by sending a sequence of malicious SIP messages to an affected device. An exploit could allow the attacker to cause a NULL pointer dereference, resulting in a crash of the iosd process. This triggers a reload of the device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-sip-dos • CWE-476: NULL Pointer Dereference •
