CVSS: 7.5EPSS: 0%CPEs: 150EXPL: 1CVE-2023-22415 – Junos OS: MX Series and SRX Series: The flow processing daemon (flowd) will crash when specific H.323 packets are received
https://notcve.org/view.php?id=CVE-2023-22415
An Out-of-Bounds Write vulnerability in the H.323 ALG of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause Denial of Service (DoS). On all MX Series and SRX Series platform, when H.323 ALG is enabled and specific H.323 packets are received simultaneously, a flow processing daemon (flowd) crash will occur. Continued receipt of these specific packets will cause a sustained Denial of Service (DoS) condition. This issue affects: Juniper Networks Junos OS on MX Series and SRX Series All versions prior to 19.4R3-S10; 20.2 versions prior to 20.2R3-S6; 20.3 versions prior to 20.3R3-S6; 20.4 versions prior to 20.4R3-S5; 21.1 versions prior to 21.1R3-S4; 21.2 versions prior to 21.2R3-S3; 21.3 versions prior to 21.3R3-S3; 21.4 versions prior to 21.4R3; 22.1 versions prior to 22.1R2-S1, 22.1R3; 22.2 versions prior to 22.2R1-S2, 22.2R2. Una vulnerabilidad de escritura fuera de los límites en el ALG H.323 de Juniper Networks Junos OS permite que un atacante basado en red no autenticado provoque una denegación de servicio (DoS). • https://kb.juniper.net/JSA70211 • CWE-787: Out-of-bounds Write •
CVSS: 5.5EPSS: 0%CPEs: 167EXPL: 0CVE-2023-22409 – Junos OS: SRX Series, MX Series with SPC3: When an inconsistent NAT configuration exists and a specific CLI command is issued the SPC will reboot
https://notcve.org/view.php?id=CVE-2023-22409
An Unchecked Input for Loop Condition vulnerability in a NAT library of Juniper Networks Junos OS allows a local authenticated attacker with low privileges to cause a Denial of Service (DoS). When an inconsistent "deterministic NAT" configuration is present on an SRX, or MX with SPC3 and then a specific CLI command is issued the SPC will crash and restart. Repeated execution of this command will lead to a sustained DoS. Such a configuration is characterized by the total number of port blocks being greater than the total number of hosts. An example for such configuration is: [ services nat source pool TEST-POOL address x.x.x.0/32 to x.x.x.15/32 ] [ services nat source pool TEST-POOL port deterministic block-size 1008 ] [ services nat source pool TEST-POOL port deterministic host address y.y.y.0/24] [ services nat source pool TEST-POOL port deterministic include-boundary-addresses] where according to the following calculation: 65536-1024=64512 (number of usable ports per IP address, implicit) 64512/1008=64 (number of port blocks per Nat IP) x.x.x.0/32 to x.x.x.15/32 = 16 (NAT IP addresses available in NAT pool) total port blocks in NAT Pool = 64 blocks per IP * 16 IPs = 1024 Port blocks host address y.y.y.0/24 = 256 hosts (with include-boundary-addresses) If the port block size is configured to be 4032, then the total port blocks are (64512/4032) * 16 = 256 which is equivalent to the total host addresses of 256, and the issue will not be seen. • https://kb.juniper.net/JSA70205 • CWE-1284: Improper Validation of Specified Quantity in Input •
CVSS: 6.5EPSS: 0%CPEs: 154EXPL: 0CVE-2023-22404 – Junos OS: SRX Series and MX Series with SPC3: When IPsec VPN is configured iked will core when a specifically formatted payload is received
https://notcve.org/view.php?id=CVE-2023-22404
An Out-of-bounds Write vulnerability in the Internet Key Exchange Protocol daemon (iked) of Juniper Networks Junos OS on SRX series and MX with SPC3 allows an authenticated, network-based attacker to cause a Denial of Service (DoS). iked will crash and restart, and the tunnel will not come up when a peer sends a specifically formatted payload during the negotiation. This will impact other IKE negotiations happening at the same time. Continued receipt of this specifically formatted payload will lead to continuous crashing of iked and thereby the inability for any IKE negotiations to take place. Note that this payload is only processed after the authentication has successfully completed. So the issue can only be exploited by an attacker who can successfully authenticate. • https://kb.juniper.net/JSA70200 • CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 0%CPEs: 90EXPL: 0CVE-2023-22412 – Junos OS: MX Series and SRX Series: The flow processing daemon (flowd) will crash if the SIP ALG is enabled and specific SIP messages are processed
https://notcve.org/view.php?id=CVE-2023-22412
An Improper Locking vulnerability in the SIP ALG of Juniper Networks Junos OS on MX Series with MS-MPC or MS-MIC card and SRX Series allows an unauthenticated, network-based attacker to cause a flow processing daemon (flowd) crash and thereby a Denial of Service (DoS). Continued receipt of these specific packets will cause a sustained Denial of Service condition. This issue occurs when SIP ALG is enabled and specific SIP messages are processed simultaneously. This issue affects: Juniper Networks Junos OS on MX Series and SRX Series 20.4 versions prior to 20.4R3-S4; 21.1 versions prior to 21.1R3-S3; 21.2 versions prior to 21.2R3-S2; 21.3 versions prior to 21.3R3; 21.4 versions prior to 21.4R3; 22.1 versions prior to 22.1R2. This issue does not affect Juniper Networks Junos OS versions prior to 20.4R1 on MX Series, or SRX Series. • https://kb.juniper.net/JSA70208 • CWE-667: Improper Locking •
CVSS: 7.5EPSS: 0%CPEs: 133EXPL: 0CVE-2023-22417 – Junos OS: SRX Series: A memory leak might be observed in IPsec VPN scenario leading to an FPC crash
https://notcve.org/view.php?id=CVE-2023-22417
A Missing Release of Memory after Effective Lifetime vulnerability in the Flow Processing Daemon (flowd) of Juniper Networks Junos OS allows a network-based, unauthenticated attacker to cause a Denial of Service (DoS). In an IPsec VPN environment, a memory leak will be seen if a DH or ECDH group is configured. Eventually the flowd process will crash and restart. This issue affects Juniper Networks Junos OS on SRX Series: All versions prior to 19.3R3-S7; 19.4 versions prior to 19.4R2-S8, 19.4R3-S10; 20.2 versions prior to 20.2R3-S6; 20.3 versions prior to 20.3R3-S5; 20.4 versions prior to 20.4R3-S5; 21.1 versions prior to 21.1R3-S4; 21.2 versions prior to 21.2R3; 21.3 versions prior to 21.3R3; 21.4 versions prior to 21.4R2.
