CVE-2019-0055 – Junos OS: SRX Series: An attacker may cause flowd to crash by sending certain valid SIP traffic to a device with SIP ALG enabled.
https://notcve.org/view.php?id=CVE-2019-0055
A vulnerability in the SIP ALG packet processing service of Juniper Networks Junos OS allows an attacker to cause a Denial of Service (DoS) to the device by sending specific types of valid SIP traffic to the device. In this case, the flowd process crashes and generates a core dump while processing SIP ALG traffic. Continued receipt of these valid SIP packets will result in a sustained Denial of Service (DoS) condition. This issue affects: Juniper Networks Junos OS: 12.3X48 versions prior to 12.3X48-D61, 12.3X48-D65 on SRX Series; 15.1X49 versions prior to 15.1X49-D130 on SRX Series; 17.3 versions prior to 17.3R3 on SRX Series; 17.4 versions prior to 17.4R2 on SRX Series. Una vulnerabilidad en el servicio de procesamiento de paquetes ALG SIP de Juniper Networks Junos OS, permite a un atacante causar una Denegación de servicio (DoS) al dispositivo mediante el envío de tipos específicos de tráfico SIP válido hacia el dispositivo. • https://kb.juniper.net/JSA10953 https://www.juniper.net/documentation/en_US/junos/topics/topic-map/security-sip-alg.html • CWE-130: Improper Handling of Length Parameter Inconsistency •
CVE-2019-0051 – SRX5000 Series: Denial of Service vulnerability in SSL-Proxy feature.
https://notcve.org/view.php?id=CVE-2019-0051
SSL-Proxy feature on SRX devices fails to handle a hardware resource limitation which can be exploited by remote SSL/TLS servers to crash the flowd daemon. Repeated crashes of the flowd daemon can result in an extended denial of service condition. For this issue to occur, clients protected by the SRX device must initiate a connection to the malicious server. This issue affects: Juniper Networks Junos OS on SRX5000 Series: 12.3X48 versions prior to 12.3X48-D85; 15.1X49 versions prior to 15.1X49-D180; 17.3 versions prior to 17.3R3-S7; 17.4 versions prior to 17.4R2-S6, 17.4R3; 18.1 versions prior to 18.1R3-S8; 18.2 versions prior to 18.2R3; 18.3 versions prior to 18.3R2; 18.4 versions prior to 18.4R2; 19.1 versions prior to 19.1R2. La funcionalidad proxy SSL en dispositivos SRX no puede manejar una limitación de recursos de hardware que puede ser explotada por servidores SSL/TLS remotos para bloquear el demonio flowd. • https://kb.juniper.net/JSA10973 • CWE-755: Improper Handling of Exceptional Conditions •
CVE-2019-0047 – Junos OS: Persistent XSS vulnerability in J-Web
https://notcve.org/view.php?id=CVE-2019-0047
A persistent Cross-Site Scripting (XSS) vulnerability in Junos OS J-Web interface may allow remote unauthenticated attackers to perform administrative actions on the Junos device. Successful exploitation requires a Junos administrator to first perform certain diagnostic actions on J-Web. This issue affects: Juniper Networks Junos OS 12.1X46 versions prior to 12.1X46-D86; 12.3 versions prior to 12.3R12-S13; 12.3X48 versions prior to 12.3X48-D80; 14.1X53 versions prior to 14.1X53-D51; 15.1 versions prior to 15.1F6-S13, 15.1R7-S4; 15.1X49 versions prior to 15.1X49-D171, 15.1X49-D180; 15.1X53 versions prior to 15.1X53-D497, 15.1X53-D69; 16.1 versions prior to 16.1R7-S5; 16.2 versions prior to 16.2R2-S9; 17.1 versions prior to 17.1R3; 17.2 versions prior to 17.2R1-S8, 17.2R2-S7, 17.2R3-S1; 17.3 versions prior to 17.3R3-S6; 17.4 versions prior to 17.4R1-S7, 17.4R2-S4, 17.4R3; 18.1 versions prior to 18.1R3-S5; 18.2 versions prior to 18.2R1-S5, 18.2R2-S3, 18.2R3; 18.3 versions prior to 18.3R1-S3, 18.3R2, 18.3R3; 18.4 versions prior to 18.4R1-S2, 18.4R2. Una vulnerabilidad de tipo Cross-Site Scripting (XSS) persistente en la interfaz J-Web de Junos OS puede permitir a atacantes remotos no autenticados realizar acciones administrativas en el dispositivo Junos. Un explotación con éxito requiere que un administrador de Junos realice primero determinadas acciones de diagnóstico en J-Web. • https://kb.juniper.net/JSA10970 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVE-2019-0053 – Junos OS: Insufficient validation of environment variables in telnet client may lead to stack-based buffer overflow
https://notcve.org/view.php?id=CVE-2019-0053
Insufficient validation of environment variables in the telnet client supplied in Junos OS can lead to stack-based buffer overflows, which can be exploited to bypass veriexec restrictions on Junos OS. A stack-based overflow is present in the handling of environment variables when connecting via the telnet client to remote telnet servers. This issue only affects the telnet client — accessible from the CLI or shell — in Junos OS. Inbound telnet services are not affected by this issue. This issue affects: Juniper Networks Junos OS: 12.3 versions prior to 12.3R12-S13; 12.3X48 versions prior to 12.3X48-D80; 14.1X53 versions prior to 14.1X53-D130, 14.1X53-D49; 15.1 versions prior to 15.1F6-S12, 15.1R7-S4; 15.1X49 versions prior to 15.1X49-D170; 15.1X53 versions prior to 15.1X53-D237, 15.1X53-D496, 15.1X53-D591, 15.1X53-D69; 16.1 versions prior to 16.1R3-S11, 16.1R7-S4; 16.2 versions prior to 16.2R2-S9; 17.1 versions prior to 17.1R3; 17.2 versions prior to 17.2R1-S8, 17.2R2-S7, 17.2R3-S1; 17.3 versions prior to 17.3R3-S4; 17.4 versions prior to 17.4R1-S6, 17.4R2-S3, 17.4R3; 18.1 versions prior to 18.1R2-S4, 18.1R3-S3; 18.2 versions prior to 18.2R1-S5, 18.2R2-S2, 18.2R3; 18.2X75 versions prior to 18.2X75-D40; 18.3 versions prior to 18.3R1-S3, 18.3R2; 18.4 versions prior to 18.4R1-S2, 18.4R2. • https://github.com/dreamsmasher/inetutils-CVE-2019-0053-Patched-PKGBUILD http://packetstormsecurity.com/files/153746/FreeBSD-Security-Advisory-FreeBSD-SA-19-12.telnet.html https://kb.juniper.net/JSA10947 https://lists.debian.org/debian-lts-announce/2022/11/msg00033.html https://lists.debian.org/debian-lts-announce/2023/10/msg00013.html https://seclists.org/bugtraq/2019/Jul/45 https://security.FreeBSD.org/advisories/FreeBSD-SA-19:12.telnet.asc https://www.exploit-db.com/exploits/45982 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •
