A vulnerability, which was classified as problematic, was found in FileZilla Server up to 0.9.50. This affects an unknown part of the component PORT Handler. The manipulation leads to unintended intermediary. It is possible to initiate the attack remotely. Upgrading to version 0.9.51 is able to address this issue. • http://www.securitygalore.com/site3/filezilla_ftp_server_advisory https://vuldb.com/?id.97203 • CWE-441: Unintended Proxy or Intermediary ('Confused Deputy') CWE-610: Externally Controlled Reference to a Resource in Another Sphere •

OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly restrict processing of ChangeCipherSpec messages, which allows man-in-the-middle attackers to trigger use of a zero-length master key in certain OpenSSL-to-OpenSSL communications, and consequently hijack sessions or obtain sensitive information, via a crafted TLS handshake, aka the "CCS Injection" vulnerability. OpenSSL anterior a 0.9.8za, 1.0.0 anterior a 1.0.0m y 1.0.1 anterior a 1.0.1h no restringe debidamente el procesamiento de mensajes ChangeCipherSpec, lo que permite a atacantes man-in-the-middle provocar el uso de una clave maestra de longitud cero en ciertas comunicaciones OpenSSL-a-OpenSSL, y como consecuencia secuestrar sesiones u obtener información sensible, a través de una negociación TLS manipulada, también conocido como la vulnerabilidad de 'inyección CCS'. It was found that OpenSSL clients and servers could be forced, via a specially crafted handshake packet, to use weak keying material for communication. A man-in-the-middle attacker could use this flaw to decrypt and modify traffic between a client and a server. • https://github.com/secretnonempty/CVE-2014-0224 https://github.com/iph0n3/CVE-2014-0224 http://aix.software.ibm.com/aix/efixes/security/openssl_advisory9.asc http://ccsinjection.lepidum.co.jp http://dev.mysql.com/doc/relnotes/workbench/en/wb-news-6-1-7.html http://esupport.trendmicro.com/solution/en-US/1103813.aspx http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10629 http://kb.juniper.net/InfoCenter/index?page=content&id=KB29195 http://kb.juniper.net/InfoCenter/ • CWE-326: Inadequate Encryption Strength CWE-841: Improper Enforcement of Behavioral Workflow •

The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to d1_both.c and t1_lib.c, aka the Heartbleed bug. Las implementaciones de (1) TLS y (2) DTLS en OpenSSL 1.0.1 en versiones anteriores a 1.0.1g no manejan adecuadamente paquetes Heartbeat Extension, lo que permite a atacantes remotos obtener información sensible desde la memoria de proceso a través de paquetes manipulados que desencadenan una sobrelectura del buffer, según lo demostrado mediante la lectura de claves privadas, relacionado con d1_both.c y t1_lib.c, también conocido como bug Heartbleed. An information disclosure flaw was found in the way OpenSSL handled TLS and DTLS Heartbeat Extension packets. A malicious TLS or DTLS client or server could send a specially crafted TLS or DTLS Heartbeat packet to disclose a limited portion of memory per request from a connected client or server. Note that the disclosed portions of memory could potentially include sensitive information such as private keys. • https://www.exploit-db.com/exploits/32764 https://www.exploit-db.com/exploits/32791 https://www.exploit-db.com/exploits/32998 https://www.exploit-db.com/exploits/32745 https://github.com/0x90/CVE-2014-0160 https://github.com/jdauphant/patch-openssl-CVE-2014-0160 https://github.com/caiqiqi/OpenSSL-HeartBleed-CVE-2014-0160-PoC https://github.com/obayesshelton/CVE-2014-0160-Scanner https://github.com/MrE-Fog/CVE-2014-0160-Chrome-Plugin https://github.com/Xyl2k/CVE-2014&# • CWE-125: Out-of-bounds Read CWE-201: Insertion of Sensitive Information Into Sent Data •

Buffer overflow in FileZilla Server before 0.9.31 allows remote attackers to cause a denial of service via unspecified vectors related to SSL/TLS packets.

FileZilla Server before 0.9.22 allows remote attackers to cause a denial of service (crash) via a wildcard argument to the (1) LIST or (2) NLST commands, which results in a NULL pointer dereference, a different set of vectors than CVE-2006-6564. NOTE: CVE analysis suggests that the problem might be due to a malformed PORT command. FileZilla Server anterior a 0.9.22 permite a un atacante remoto provocar denegación de servicio (caida) a través del argumento wildcard a los comandos (1) LIST o (2) NLST, lo cual resulta en un puntero NULL no referenciado, un grupo diferente de vectores que CVE-2006-????. NOTA: el análisis CVE sugiere que el problema pudo ser debido a un comando PORT malformado. • https://www.exploit-db.com/exploits/2914 http://sourceforge.net/project/shownotes.php?release_id=470364&group_id=21558 http://www.vupen.com/english/advisories/2006/4937 https://exchange.xforce.ibmcloud.com/vulnerabilities/30853 • CWE-476: NULL Pointer Dereference •
