This issue affects: o Juniper Networks CTPView and CTPOS 7.3 versions prior to 7.3R6. No other versions of CTPView and CTPOS are affected by these vulnerabilities. This issue was discovered during an external security research. The resolved issues include: CVE CVSS Summary The do_setup_env function in session.c in sshd in OpenSSH through 7.2p2, when the UseLogin feature 7.8 ( CVSS:3.0 is enabled and PAM is configured to read CVE-2015-8325 /AV:L/AC:L/ .pam_environment files in user home directories, PR:L/UI:N/S:U/ allows local users to gain privileges by C:H/I:H/A:H ) triggering a crafted environment for the /bin/ login program, as demonstrated by an LD_PRELOAD environment variable. 7.0 ( CVSS:3.0 sshd in OpenSSH before 7.4, when privilege /AV:L/AC:H/ separation is not used, creates forwarded CVE-2016-10010 PR:L/UI:N/S:U/ Unix-domain sockets as root, which might allow C:H/I:H/A:H ) local users to gain privileges via unspecified vectors, related to serverloop.c. authfile.c in sshd in OpenSSH before 7.4 does not 5.5 ( CVSS:3.0 properly consider the effects of realloc on CVE-2016-10011 /AV:L/AC:L/ buffer contents, which might allow local users to PR:L/UI:N/S:U/ obtain sensitive private-key information by C:H/I:N/A:N ) leveraging access to a privilege-separated child process. The shared memory manager (associated with pre-authentication compression) in sshd in 7.8 ( CVSS:3.0 OpenSSH before 7.4 does not ensure that a bounds CVE-2016-10012 /AV:L/AC:L/ check is enforced by all compilers, which might PR:L/UI:N/S:U/ allows local users to gain privileges by C:H/I:H/A:H ) leveraging access to a sandboxed privilege-separation process, related to the m_zback and m_zlib data structures. 7.3 ( CVSS:3.0 Untrusted search path vulnerability in /AV:N/AC:L/ ssh-agent.c in ssh-agent in OpenSSH before 7.4 CVE-2016-10009 PR:N/UI:N/S:U/ allows remote attackers to execute arbitrary C:L/I:L/A:L ) local PKCS#11 modules by leveraging control over a forwarded agent-socket. 5.3 ( CVSS:3.0 In OpenSSH 7.9, scp.c in the scp client allows /AV:N/AC:H/ remote SSH servers to bypass intended access CVE-2018-20685 PR:N/UI:R/S:U/ restrictions via the filename of . or an empty C:N/I:H/A:N ) filename. The impact is modifying the permissions of the target directory on the client side. Solution: These vulnerabilities are resolved in CTPView and CTPOS 7.3R6 and all subsequent releases. This issue is being tracked as PR 1438378 and 1455669 which are visible on the Customer Support website. Note: Juniper SIRT's policy is not to evaluate releases which are beyond End of Engineering (EOE) or End of Life (EOL). Workaround: Use access lists or firewalls to limit access to the device only from trusted hosts.
