The Intersil isl3893 extensions for Boa 0.93.15, as used on the FreeLan RO80211G-AP and other devices, do not prevent stack writes from entering memory locations used for string constants, which allows remote attackers to change the admin password stored in memory via a long username in an HTTP Basic Authentication request.

Boa through 0.94.14rc21 allows remote attackers to trigger an out-of-memory (OOM) condition because malloc is mishandled.

Boa 0.94.14rc21 is vulnerable to SQL Injection via username.

DISPUTED /cgi-bin/wapopen in Boa 0.94.14rc21 allows the injection of "../.." using the FILECAMERA variable (sent by GET) to read files with root privileges. NOTE: multiple third parties report that this is a system-integrator issue (e.g., a vulnerability on one type of camera) because Boa does not include any wapopen program or any code to read a FILECAMERA variable.

Buffer overflow in sendredirect() in Boa Webserver 0.92r allows remote attackers to DoS via an HTTP GET request requesting a long URI with only '/' and '.' characters.

DISPUTED Boa 0.94.13 allows remote attackers to obtain sensitive information via a misconfiguration involving backup.html, preview.html, js/log.js, log.html, email.html, online-users.html, and config.js. NOTE: multiple third parties report that this is a site-specific issue because those files are not part of Boa.

Boa through 0.94.14rc21 allows remote attackers to trigger a memory leak because of missing calls to the free function.

A vulnerability has been found in D-Link DCS-5615 1.01.00. Affected by this vulnerability is an unknown functionality of the file /etc/conf.d/boa/boa.conf of the component Boa Webserver. Such manipulation leads to least privilege violation. The attack can be executed remotely. The exploit has been disclosed to the public and may be used.

An OS command injection vulnerability exists in PLDT WiFi Router's Prolink PGN6401V Firmware 8.1.2 web management interface. The ping6.asp page submits user input to the /boaform/formPing6 endpoint via the pingAddr parameter, which is not properly sanitized. An authenticated attacker can exploit this flaw by injecting arbitrary system commands, which are executed by the underlying operating system with root privileges. The router uses the Boa web server (version 0.93.15) to handle the request. Successful exploitation can lead to full system compromise and unauthorized control of the network device.

Boa Web Server versions 0.94.13 through 0.94.14 fail to validate the correct security constraint on the HEAD HTTP method allowing everyone to bypass the Basic Authorization mechanism.

Directory traversal vulnerability in BOA web server 0.94.8.2 and earlier allows remote attackers to read arbitrary files via a modified .. (dot dot) attack in the GET HTTP request that uses a "%2E" instead of a "."

Boa 0.94.14rc21 writes data to a log file without sanitizing non-printable characters, which might allow remote attackers to modify a window's title, or possibly execute arbitrary commands or overwrite files, via an HTTP request containing an escape sequence for a terminal emulator.
