| CVE-2018-15399 | 1 Cisco | 2 Adaptive Security Appliance Software, Firepower Threat Defense | 2024-02-28 | 7.1 HIGH | 6.8 MEDIUM |
| A vulnerability in the TCP syslog module of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to exhaust the 1550-byte buffers on an affected device, resulting in a denial of service (DoS) condition. The vulnerability is due to a missing boundary check in an internal function. An attacker could exploit this vulnerability by establishing a man-in-the-middle position between an affected device and its configured TCP syslog server and then maliciously modifying the TCP header in segments that are sent from the syslog server to the affected device. A successful exploit could allow the attacker to exhaust buffer on the affected device and cause all TCP-based features to stop functioning, resulting in a DoS condition. The affected TCP-based features include AnyConnect SSL VPN, clientless SSL VPN, and management connections such as Secure Shell (SSH), Telnet, and HTTPS. | |||||
| CVE-2018-15383 | 1 Cisco | 2 Adaptive Security Appliance Software, Firepower Threat Defense | 2024-02-28 | 7.8 HIGH | 7.5 HIGH |
| A vulnerability in the cryptographic hardware accelerator driver of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a temporary denial of service (DoS) condition. The vulnerability exists because the affected devices have a limited amount of Direct Memory Access (DMA) memory and the affected software improperly handles resources in low-memory conditions. An attacker could exploit this vulnerability by sending a sustained, high rate of malicious traffic to an affected device to exhaust memory on the device. A successful exploit could allow the attacker to exhaust DMA memory on the affected device, which could cause the device to reload and result in a temporary DoS condition. | |||||
| CVE-2018-15465 | 1 Cisco | 1 Adaptive Security Appliance Software | 2024-02-28 | 5.5 MEDIUM | 8.1 HIGH |
| A vulnerability in the authorization subsystem of Cisco Adaptive Security Appliance (ASA) Software could allow an authenticated, but unprivileged (levels 0 and 1), remote attacker to perform privileged actions by using the web management interface. The vulnerability is due to improper validation of user privileges when using the web management interface. An attacker could exploit this vulnerability by sending specific HTTP requests via HTTPS to an affected device as an unprivileged user. An exploit could allow the attacker to retrieve files (including the running configuration) from the device or to upload and replace software images on the device. | |||||
| CVE-2018-15397 | 1 Cisco | 2 Adaptive Security Appliance Software, Firepower Management Center | 2024-02-28 | 7.1 HIGH | 6.8 MEDIUM |
| A vulnerability in the implementation of Traffic Flow Confidentiality (TFC) over IPsec functionality in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an affected device to restart unexpectedly, resulting in a denial of service (DoS) condition. The vulnerability is due to an error that may occur if the affected software renegotiates the encryption key for an IPsec tunnel when certain TFC traffic is in flight. An attacker could exploit this vulnerability by sending a malicious stream of TFC traffic through an established IPsec tunnel on an affected device. A successful exploit could allow the attacker to cause a daemon process on the affected device to crash, which could cause the device to crash and result in a DoS condition. | |||||
| CVE-2018-0242 | 1 Cisco | 11 Adaptive Security Appliance Software, Asa 5506-x, Asa 5506h-x and 8 more | 2024-02-28 | 4.3 MEDIUM | 6.1 MEDIUM |
| A vulnerability in the WebVPN web-based management interface of Cisco Adaptive Security Appliance could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based management interface of an affected device. The vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected device. An attacker could exploit this vulnerability by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or allow the attacker to access sensitive browser-based information. Cisco Bug IDs: CSCvg33985. | |||||
| CVE-2018-0230 | 1 Cisco | 2 Adaptive Security Appliance Software, Firepower Threat Defense | 2024-02-28 | 7.8 HIGH | 8.6 HIGH |
| A vulnerability in the internal packet-processing functionality of Cisco Firepower Threat Defense (FTD) Software for Cisco Firepower 2100 Series Security Appliances could allow an unauthenticated, remote attacker to cause an affected device to stop processing traffic, resulting in a denial of service (DoS) condition. The vulnerability is due to the affected software improperly validating IP Version 4 (IPv4) and IP Version 6 (IPv6) packets after the software reassembles the packets (following IP Fragmentation). An attacker could exploit this vulnerability by sending a series of malicious, fragmented IPv4 or IPv6 packets to an affected device. A successful exploit could allow the attacker to cause Snort processes on the affected device to hang at 100% CPU utilization, which could cause the device to stop processing traffic and result in a DoS condition until the device is reloaded manually. This vulnerability affects Cisco Firepower Threat Defense (FTD) Software Releases 6.2.1 and 6.2.2, if the software is running on a Cisco Firepower 2100 Series Security Appliance. Cisco Bug IDs: CSCvf91098. | |||||
| CVE-2018-0229 | 1 Cisco | 2 Adaptive Security Appliance Software, Anyconnect Secure Mobility Client | 2024-02-28 | 4.3 MEDIUM | 6.5 MEDIUM |
| A vulnerability in the implementation of Security Assertion Markup Language (SAML) Single Sign-On (SSO) authentication for Cisco AnyConnect Secure Mobility Client for Desktop Platforms, Cisco Adaptive Security Appliance (ASA) Software, and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to establish an authenticated AnyConnect session through an affected device running ASA or FTD Software. The authentication would need to be done by an unsuspecting third party, aka Session Fixation. The vulnerability exists because there is no mechanism for the ASA or FTD Software to detect that the authentication request originates from the AnyConnect client directly. An attacker could exploit this vulnerability by persuading a user to click a crafted link and authenticating using the company's Identity Provider (IdP). A successful exploit could allow the attacker to hijack a valid authentication token and use that to establish an authenticated AnyConnect session through an affected device running ASA or FTD Software. This vulnerability affects the Cisco AnyConnect Secure Mobility Client, and ASA Software and FTD Software configured for SAML 2.0-based SSO for AnyConnect Remote Access VPN that is running on the following Cisco products: 3000 Series Industrial Security Appliances (ISA), ASA 5500 Series Adaptive Security Appliances, ASA 5500-X Series Next-Generation Firewalls, ASA Services Module for Cisco Catalyst 6500 Series Switches and Cisco 7600 Series Routers, Adaptive Security Virtual Appliance (ASAv), Firepower 2100 Series Security Appliance, Firepower 4100 Series Security Appliance, Firepower 9300 ASA Security Module, FTD Virtual (FTDv). Cisco Bug IDs: CSCvg65072, CSCvh87448. | |||||
