AlienVault OTX Vulnerabilities

AlienVault OTX Malware

A vulnerability in the HTTP Server feature of Cisco IOS Software and Cisco IOS XE Software Release 3E could allow an authenticated, remote attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition.
 This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending malformed HTTP requests to an affected device. A successful exploit could allow the attacker to cause a watchdog timer to expire and the device to reload, resulting in a DoS condition. To exploit this vulnerability, the attacker must have a valid user account.

CVE-2026-20125 is a vulnerability identified in the HTTP Server feature of Cisco IOS and IOS XE software, spanning numerous versions including many 12.x and 15.x releases. The root cause is improper validation of user-supplied input within the HTTP server component. An authenticated remote attacker with a valid user account can exploit this flaw by sending specially crafted malformed HTTP requests to the affected device. This malformed input causes the device's watchdog timer to expire, which triggers an automatic device reload, resulting in a denial of service (DoS) condition. The vulnerability does not impact confidentiality or integrity but severely affects availability by causing unexpected device reboots. The attack vector is network-based (AV:N), requires low attack complexity (AC:L), and privileges (PR:L) but no user interaction (UI:N). The scope is changed (S:C) as the impact affects components beyond the vulnerable HTTP server. The CVSS v3.1 base score is 7.7, indicating high severity. Although no known exploits have been reported in the wild, the extensive list of affected Cisco IOS versions and the critical role of these devices in network infrastructure make this a significant threat. The vulnerability primarily targets network infrastructure devices such as routers and switches running the affected Cisco IOS versions, which are widely deployed in enterprise, service provider, and government networks worldwide.
