Monkey-project : Security Vulnerabilities, CVEs,

Monkey HTTP Server before 1.5.3, when the File Descriptor Table (FDT) is enabled and custom error messages are set, allows remote attackers to cause a denial of service (file descriptor consumption) via an HTTP request that triggers an error message.

Stack-based buffer overflow in the mk_request_header_process function in mk_request.c in Monkey HTTP Daemon (monkeyd) before 1.2.1 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted HTTP header.

The mk_request_header_process function in mk_request.c in Monkey 1.1.1 allows remote attackers to cause a denial of service (thread crash and service outage) via a '\0' character in an HTTP request.

Monkey HTTP Daemon has local security bypass

The Mandril security plugin in Monkey HTTP Daemon (monkeyd) before 1.5.0 allows remote attackers to bypass access restrictions via a crafted URI, as demonstrated by an encoded forward slash.

Cross-site scripting (XSS) vulnerability in the Directory Listing plugin in Monkey HTTP Daemon (monkeyd) 1.2.2 allows attackers to inject arbitrary web script or HTML via a file name.

Monkey HTTP Daemon (monkeyd) before 1.2.2 allows remote attackers to cause a denial of service (infinite loop) via an offset equal to the file size in the Range HTTP header.

Monkey HTTP Daemon: broken user name authentication

The web server Monkeyd produces a world-readable log (/var/log/monkeyd/master.log) on gentoo.

Monkey HTTP Daemon 0.9.3 might allow local users to overwrite arbitrary files via a symlink attack on a PID file, as demonstrated by a pathname different from the default /var/run/monkey.pid pathname.

Monkey HTTP Daemon 0.9.3 uses a real UID of root and a real GID of root during execution of CGI scripts, which might allow local users to gain privileges by leveraging cgi-bin write access.

Monkey HTTP Daemon 0.9.3 retains the supplementary group IDs of the root account during operations with a non-root effective UID, which might allow local users to bypass intended file-read restrictions by leveraging a race condition in a file-permission check.

Monkey daemon (monkeyd) before 0.9.1 allows remote attackers to cause a denial of service (memory corruption) via a request for a zero byte file.

Format string vulnerability in cgi.c for Monkey daemon (monkeyd) before 0.9.1 allows remote attackers to cause a denial of service and possibly execute arbitrary code via an HTTP GET request containing double-encoded format string specifiers (aka "double expansion error").

The get_real_string function in Monkey HTTP Daemon (monkeyd) 0.8.1 and earlier allows remote attackers to cause a denial of service (crash) via an HTTP request with a sequence of "%" characters and a missing Host field.

The Post_Method function in Monkey HTTP Daemon before 0.6.2 allows remote attackers to cause a denial of service (crash) via a POST request without a Content-Type header.

Buffer overflow in PostMethod() function for Monkey HTTP Daemon (monkeyd) 0.6.1 and earlier allows remote attackers to execute arbitrary code via a POST request with a large body.

Directory traversal vulnerability in Monkey HTTP Daemon 0.1.4 allows remote attackers to read arbitrary files via .. (dot dot) sequences.

Cross-site scripting (XSS) vulnerability in Monkey 0.5.0 allows remote attackers to inject arbitrary web script or HTML via (1) the URL or (2) a parameter to test2.pl.

The Post_Method function in method.c for Monkey HTTP Daemon before 0.5.1 allows remote attackers to cause a denial of service (crash) via a POST request with an invalid or missing Content-Length header value.
