Critical vManage Security BugsvManage is a centralized network management system that provides a GUI interface to easily monitor, configure and maintain all devices and links in the overlay SD-WAN. According to Cisco\u2019s Wednesday advisory, there are five security holes in the software, the first four only exploitable if the platform is running in cluster mode:\n\n* CVE-2021-1468: Critical Unauthorized Message-Processing Vulnerability (RCE)\n* CVE-2021-1505: Critical Privilege-Escalation Vulnerability\n* CVE-2021-1508: High-Severity Unauthorized-Access Vulnerability\n* CVE-2021-1506: High-Severity Unauthorized Services-Access Vulnerability\n* CVE-2021-1275: High-Severity Denial-of-Service Vulnerability\nSee Also: Hundreds of Millions of Dell Users at Risk from Kernel-Privilege Bugs\nThe issue tracked as CVE-2021-1468 is the most severe of the five, carrying a CVSS vulnerability-severity score of 9.8 out of 10. It exists in messaging service used by vManage, and is due to improper authentication checks on user-supplied input to an application messaging service, according to Cisco.\n\nUnauthenticated, remote adversaries could mount a cyberattack by submitting crafted input to the service. That would allow them to call privileged actions within the affected system, including creating new administrative level user accounts, the advisory said.\n\nMeanwhile, the local privilege-escalation (LPE) bug tracked as CVE-2021-1505 has a CVSS score of 9.1. It exists in the web-based management interface of vManage and would allow an authenticated, remote attacker to bypass authorization checking to gain elevated privileges within the system.\n\nSimilarly, CVE-2021-1508, which has a CVSS score of 8.1, is an LPE bug that can also be found in the web-based management interface. It would also allow an authenticated, remote attacker to bypass authorization checking in order to gain access to forbidden applications, make application modifications and also gain elevated privileges.\n\nBoth local bugs exist \u201cbecause the affected software does not perform authorization checks on certain operations,\u201d according to Cisco.\n\nA third locally exploitable bug, CVE-2021-1506, carries a CVSS score of 7.2. It allows an authenticated, remote attacker to gain unauthorized access to services within an affected system, because the system doesn\u2019t perform authorization checks on service access.\n\nAnd in all three local cases, an attacker could trigger exploits by sending crafted requests to the affected system.\nSee Also: Offensive Security Tool: SSHPry2.0\nAnd finally, the CVE-2021-1275 DoS flaw (CVSS score 7.5) exists in a vManage API. Attackers can send a large amount of API requests to a target system to tie [...]\n\n___________________________ \n@hacking_Attack\n@Hacking_Video", "creation_timestamp": "2026-09-01T20:02:44.387900Z"}
