CVSS: 10.0EPSS: 83%CPEs: 361EXPL: 0CVE-2020-10188 – telnet-server: no bounds checks in nextitem() function allows to remotely execute arbitrary code
https://notcve.org/view.php?id=CVE-2020-10188
utility.c in telnetd in netkit telnet through 0.17 allows remote attackers to execute arbitrary code via short writes or urgent data, because of a buffer overflow involving the netclear and nextitem functions. El archivo utility.c en telnetd en netkit telnet versiones hasta 0.17, permite a atacantes remotos ejecutar código arbitrario por medio de escrituras cortas o datos urgentes, debido a un desbordamiento del búfer que involucra a las funciones netclear y nextitem. A vulnerability was found where incorrect bounds checks in the telnet server’s (telnetd) handling of short writes and urgent data, could lead to information disclosure and corruption of heap data. An unauthenticated remote attacker could exploit these bugs by sending specially crafted telnet packets to achieve arbitrary code execution in the telnet server. • https://appgateresearch.blogspot.com/2020/02/bravestarr-fedora-31-netkit-telnetd_28.html https://github.com/krb5/krb5-appl/blob/d00cd671dfe945791b33d4f1f6a5c57ae1667ef8/telnet/telnetd/utility.c#L205-L216 https://lists.debian.org/debian-lts-announce/2020/05/msg00012.html https://lists.debian.org/debian-lts-announce/2020/08/msg00038.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/7FMTRRQTYKWZD2GMXX3GLZV46OLPCLVK https://lists.fedoraproject.org/archives/list/package-announce%40l • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVSS: 6.5EPSS: 0%CPEs: 53EXPL: 0CVE-2015-5361 – Junos: FTPS through SRX opens up wide range of data channel TCP ports
https://notcve.org/view.php?id=CVE-2015-5361
Background For regular, unencrypted FTP traffic, the FTP ALG can inspect the unencrypted control channel and open related sessions for the FTP data channel. These related sessions (gates) are specific to source and destination IPs and ports of client and server. The design intent of the ftps-extensions option (which is disabled by default) is to provide similar functionality when the SRX secures the FTP/FTPS client. As the control channel is encrypted, the FTP ALG cannot inspect the port specific information and will open a wider TCP data channel (gate) from client IP to server IP on all destination TCP ports. In FTP/FTPS client environments to an enterprise network or the Internet, this is the desired behavior as it allows firewall policy to be written to FTP/FTPS servers on well-known control ports without using a policy with destination IP ANY and destination port ANY. • https://kb.juniper.net/JSA10706 • CWE-326: Inadequate Encryption Strength •
