Unauthenticated Buffer Overflow Vulnerability in the Utility Daemon Accessed via the PAPI Protocol (CVE-2024-26305)

This buffer overflow vulnerability exists in the underlying Utility daemon. An unauthenticated attacker may exploit the vulnerability by sending specially crafted packets destined for the PAPI (Aruba’s access point management protocol) UDP port (8211). Successful exploitation of this vulnerability may allow an attacker to execute arbitrary code as a privileged user on the underlying operating system.

Unauthenticated Buffer Overflow Vulnerability in the L2/L3 Management Service Accessed via the PAPI Protocol (CVE-2024-26304)

This buffer overflow vulnerability exists in the underlying L2/L3 Management service. An unauthenticated may exploit the vulnerability by sending specially crafted packets destined to the PAPI (Aruba’s access point management protocol) UDP port (8211). Successful exploitation of this vulnerability may allow an attacker to perform remote code execution as a privileged user on the underlying operating system.

Unauthenticated Buffer Overflow Vulnerability in the Automatic Reporting Service Accessed via the PAPI Protocol (CVE-2024-33511)

This buffer overflow vulnerability exists in the underlying Automatic Reporting service. An unauthenticated attacker may exploit the vulnerability by sending specially crafted packets destined to the PAPI (Aruba’s access point management protocol) UDP port (8211). On successful exploitation, an attacker may perform remote code execution as a privileged user on the underlying operating system.

Unauthenticated Buffer Overflow Vulnerability in the Local User Authentication Database Accessed via the PAPI Protocol (CVE-2024-33512)

This buffer overflow vulnerability in the underlying Local User Authentication Database service. An unauthenticated attacker may exploit the vulnerability by sending specially crafted packets destined to the PAPI (Aruba’s access point management protocol) UDP port (8211). Successful exploitation of this vulnerability may allow an attacker to execute arbitrary code as a privileged user on the underlying operating system.
