Vulnerabilidades

Xlight FTP v3.9.3.2 was discovered to contain a stack-based buffer overflow which allows attackers to leak sensitive information via crafted code.

options.c in atftp before 0.7.5 reads past the end of an array, and consequently discloses server-side /etc/group data to a remote client.

tftpd_file.c in atftp through 0.7.4 has a buffer overflow because buffer-size handling does not properly consider the combination of data, OACK, and other options.

Issues were discovered in Open TFTP Server multithreaded 1.66 and Open TFTP Server single port 1.66. Due to insufficient access restrictions in the default installation directory, an attacker can elevate privileges by replacing the OpenTFTPServerMT.exe or the OpenTFTPServerSP.exe binary.

An exploitable denial of service vulnerability exists in the atftpd daemon functionality of atftp 0.7.git20120829-3.1+b1. A specially crafted sequence of RRQ-Multicast requests trigger an assert() call resulting in denial-of-service. An attacker can send a sequence of malicious packets to trigger this vulnerability.

Stack-based overflow vulnerability in the logMess function in Open TFTP Server SP 1.66 and earlier allows remote attackers to perform a denial of service or execute arbitrary code via a long TFTP error packet, a different vulnerability than CVE-2018-10387 and CVE-2019-12567.

Stack-based overflow vulnerability in the logMess function in Open TFTP Server MT 1.65 and earlier allows remote attackers to perform a denial of service or execute arbitrary code via a long TFTP error packet, a different vulnerability than CVE-2018-10387 and CVE-2019-12568.

Format string vulnerability in the logMess function in TFTP Server MT 1.65 and earlier allows remote attackers to perform a denial of service or execute arbitrary code via format string sequences in a TFTP error packet.

Format string vulnerability in the logMess function in TFTP Server SP 1.66 and earlier allows remote attackers to perform a denial of service or execute arbitrary code via format string sequences in a TFTP error packet.

Heap-based overflow vulnerability in TFTP Server SP 1.66 and earlier allows remote attackers to perform a denial of service or possibly execute arbitrary code via a long TFTP error packet, a different vulnerability than CVE-2008-2161.

An issue was discovered in atftpd in atftp 0.7.1. It does not lock the thread_list_mutex mutex before assigning the current thread data structure. As a result, the daemon is vulnerable to a denial of service attack due to a NULL pointer dereference. If thread_data is NULL when assigned to current, and modified by…

An issue was discovered in atftpd in atftp 0.7.1. A remote attacker may send a crafted packet triggering a stack-based buffer overflow due to an insecurely implemented strncpy call. The vulnerability is triggered by sending an error packet of 3 bytes or fewer. There are multiple instances of this vulnerable strncpy…

LightFTP version 1.1 is vulnerable to a buffer overflow in the "writelogentry" function resulting a denial of services or a remote code execution.

Directory traversal vulnerability in the TFTP Server 1.0.0.24 in Ipswitch WhatsUp Gold allows remote attackers to read arbitrary files via a .. (dot dot) in the Filename field of an RRQ operation.

Hillstone HS TFTP Server 1.3.2 allows remote attackers to cause a denial of service (daemon crash) via a long filename in a (1) RRQ or (2) WRQ operation.

Format string vulnerability in the client in Tftpd32 before 4.50 allows remote servers to cause a denial of service (crash) or possibly execute arbitrary code via format string specifiers in the Remote File field.

Untrusted search path vulnerability in SmartFTP 4.0.1140.0 allows local users to gain privileges via a Trojan horse dwmapi.dll file in the current working directory, as demonstrated by a directory that contains a .txt, .html, or .mpg file. NOTE: some of these details are obtained from third party information.

Buffer overflow in tftp-hpa before 5.1 allows remote attackers to cause a denial of service and possibly execute arbitrary code via the utimeout option.

Unspecified vulnerability in SmartFTP before 4.0 Build 1142 allows attackers to have an unknown impact via a long filename.

Stack-based buffer overflow in AmmSoft ScriptFTP 3.3 allows remote FTP servers to execute arbitrary code via a long filename in a response to a LIST command, as demonstrated using (1) GETLIST or (2) GETFILE in a ScriptFTP script.

Directory traversal vulnerability in SmartSoft Ltd SmartFTP Client 4.0.1124.0, and possibly other versions before 4.0 Build 1133, allows remote FTP servers to overwrite arbitrary files via a "..\" (dot dot backslash) in a filename. NOTE: some of these details are obtained from third party information.

Directory traversal vulnerability in the SFTP/SSH2 virtual server in Xlight FTP Server 3.5.0, 3.5.5, and possibly other versions before 3.6 allows remote authenticated users to read, overwrite, or delete arbitrary files via .. (dot dot) sequences in the (1) ls, (2) rm, (3) rename, and other unspecified commands.

SolarWinds TFTP Server 10.4.0.13 allows remote attackers to cause a denial of service (crash) via a long write request.

SolarWinds TFTP Server 10.4.0.10 allows remote attackers to cause a denial of service (no new connections) via a crafted read request.

Buffer overflow in k23productions TFTPUtil GUI (aka TFTPGUI) 1.4.5 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long transport mode.
