CVE-2019-12658 – Cisco IOS XE Software Filesystem Exhaustion Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2019-12658
A vulnerability in the filesystem resource management code of Cisco IOS XE Software could allow an unauthenticated, remote attacker to exhaust filesystem resources on an affected device and cause a denial of service (DoS) condition. The vulnerability is due to ineffective management of the underlying filesystem resources. An attacker could exploit this vulnerability by performing specific actions that result in messages being sent to specific operating system log files. A successful exploit could allow the attacker to exhaust available filesystem space on an affected device. This could cause the device to crash and reload, resulting in a DoS condition for clients whose network traffic is transiting the device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190925-iosxe-fsdos • CWE-400: Uncontrolled Resource Consumption •
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 •
CVE-2019-12643 – Cisco REST API Container for IOS XE Software Authentication Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2019-12643
A vulnerability in the Cisco REST API virtual service container for Cisco IOS XE Software could allow an unauthenticated, remote attacker to bypass authentication on the managed Cisco IOS XE device. The vulnerability is due to an improper check performed by the area of code that manages the REST API authentication service. An attacker could exploit this vulnerability by submitting malicious HTTP requests to the targeted device. A successful exploit could allow the attacker to obtain the token-id of an authenticated user. This token-id could be used to bypass authentication and execute privileged actions through the interface of the REST API virtual service container on the affected Cisco IOS XE device. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20190828-iosxe-rest-auth-bypass • CWE-287: Improper Authentication •
