**DISPUTED**A failure in the -fstack-protector feature in GCC-based toolchains that target AArch64 allows an attacker to exploit an existing buffer overflow in dynamically-sized local variables in your application without this being detected. This stack-protector failure only applies to C99-style dynamically-sized local variables or those created using alloca(). The stack-protector operates as intended for statically-sized local variables. The default behavior when the stack-protector detects an overflow is to terminate your application, resulting in controlled loss of availability. An attacker who can exploit a buffer overflow without triggering the stack-protector might be able to change program flow control to cause an uncontrolled loss of availability or to go further and affect confidentiality or integrity. NOTE: The GCC project argues that this is a missed hardening bug and not a vulnerability by itself.

SSZipArchive versions 2.5.3 and older contain an arbitrary file write vulnerability due to lack of sanitization on paths which are symlinks. SSZipArchive will overwrite files on the filesystem when opening a malicious ZIP containing a symlink as the first item.

MITRE CALDERA 4.1.0 allows stored XSS via app.contact.gist (aka the gist contact configuration field), leading to execution of arbitrary commands on agents.

An authenticated attacker can enumerate and download sensitive files, including the eNodeB's web management UI's TLS private key, the web server binary, and the web server configuration file. These vulnerabilities were found in AirVelocity 1500 running software version 9.3.0.01249, were still present in 15.18.00.2511, and may affect other AirVelocity and AirSpeed models.

The AirVelocity 1500 prints SNMP credentials on its physically accessible serial port during boot. This was fixed in AirVelocity 1500 software version 15.18.00.2511 and may affect other AirVelocity and AirSpeed models.

Airspan AirVelocity 1500 web management UI displays SNMP credentials in plaintext on software versions older than 15.18.00.2511, and stores SNMPv3 credentials unhashed on the filesystem, enabling anyone with web access to use these credentials to manipulate the eNodeB over SNMP. This issue may affect other AirVelocity and AirSpeed models.

Airspan AirVelocity 1500 software versions prior to 15.18.00.2511 have a root command injection vulnerability in the ActiveBank parameter of the recoverySubmit.cgi script running on the eNodeB's web management UI. This issue may affect other AirVelocity and AirSpeed models.

Airspan AirVelocity 1500 software prior to version 15.18.00.2511 had NET-SNMP-EXTEND-MIB enabled on its snmpd service, enabling an attacker with SNMP write abilities to execute commands as root on the eNodeB. This issue may affect other AirVelocity and AirSpeed models.

A race condition exists in Eternal Terminal prior to version 6.2.0 that allows an authenticated attacker to hijack other users' SSH authorization socket, enabling the attacker to login to other systems as the targeted users. The bug is in UserTerminalRouter::getInfoForId().

A race condition exists in Eternal Terminal prior to version 6.2.0 which allows a local attacker to hijack Eternal Terminal's IPC socket, enabling access to Eternal Terminal clients which attempt to connect in the future.

Several denial of service vulnerabilities exist in Eternal Terminal prior to version 6.2.0, including a DoS triggered remotely by an invalid sequence number and a local bug triggered by invalid input sent directly to the IPC socket.

A privilege escalation to root exists in Eternal Terminal prior to version 6.2.0. This is due to the combination of a race condition, buffer overflow, and logic bug all in PipeSocketHandler::listen().
