CVE-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') •
CVE-2019-12666 – Cisco IOS XE Software Path Traversal Vulnerability
https://notcve.org/view.php?id=CVE-2019-12666
A vulnerability in the Guest Shell of Cisco IOS XE Software could allow an authenticated, local attacker to perform directory traversal on the base Linux operating system of Cisco IOS XE Software. The vulnerability is due to incomplete validation of certain commands. An attacker could exploit this vulnerability by first accessing the Guest Shell and then entering specific commands. A successful exploit could allow the attacker to execute arbitrary code on the base Linux operating system. Una vulnerabilidad en el Guest Shell del Software Cisco IOS XE, podría permitir a un atacante local autenticado realizar un salto de directorio en el sistema operativo base Linux del software Cisco IOS XE. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-dt • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVE-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 •
CVE-2019-12667 – Cisco IOS XE Software Stored Cross-Site Scripting Vulnerability
https://notcve.org/view.php?id=CVE-2019-12667
A vulnerability in the web framework code of 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. The vulnerability is due to insufficient input validation of some parameters that are passed to the web server of the affected software. An attacker could exploit this vulnerability by convincing a user of the web interface to access a malicious link or by intercepting a user request for the affected web interface 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. Una vulnerabilidad en el código del framework web del Software Cisco IOS XE, podría permitir a un atacante remoto autenticado realizar un ataque de tipo cross-site scripting (XSS) almacenado contra un usuario de la interfaz web del software afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-xss • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVE-2019-12646 – Cisco IOS XE Software NAT Session Initiation Protocol Application Layer Gateway Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-12646
A vulnerability in the Network Address Translation (NAT) Session Initiation Protocol (SIP) Application Layer Gateway (ALG) of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to improper processing of transient SIP packets on which NAT is performed on an affected device. An attacker could exploit this vulnerability by using UDP port 5060 to send crafted SIP packets through an affected device that is performing NAT for SIP packets. A successful exploit could allow an attacker to cause the device to reload, resulting in a denial of service (DoS) condition. Una vulnerabilidad en el Network Address Translation (NAT) Session Initiation Protocol (SIP) Application Layer Gateway (ALG) del Software Cisco IOS XE, podría permitir a un atacante remoto no autenticado causar que un dispositivo afectado se recargue. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-sip-alg • CWE-399: Resource Management Errors CWE-665: Improper Initialization •
