TITLE

plural D-Link Information disclosure vulnerability in products

Trust: 0.8

sources: JVNDB: JVNDB-2018-013711

DESCRIPTION

An issue was discovered on D-Link DWR-116 through 1.06, DIR-140L through 1.02, DIR-640L through 1.02, DWR-512 through 2.02, DWR-712 through 2.02, DWR-912 through 2.02, DWR-921 through 2.02, and DWR-111 through 1.01 devices. The administrative password is stored in plaintext in the /tmp/csman/0 file. An attacker having a directory traversal (or LFI) can easily get full router access. plural D-Link The product contains an information disclosure vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. DWR-116, DIR-140, DIR-640, etc. are all D-Link router products. There are password plaintext storage vulnerabilities in multiple series of D-Link routers. D-Link DWR-116, etc. The following products and versions are affected: D-Link DWR-116 1.06 and earlier; DIR-140L 1.02 and earlier; DIR-640L 1.02 and earlier; DWR-512 2.02 and earlier; DWR-712 2.02 and earlier; DWR-912 2.02 and earlier; DWR-921 2.02 and earlier; DWR-111 1.01 and earlier. aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa MULTIPLE VULNERABILITIES IN D-LINK ROUTERS Blazej Adamczyk (br0x) blazej.adamczyk@gmail.com http://sploit.tech/ aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa 12.10.2018 1 Directory Traversal in httpd server in several series of D-Link routers aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aa CVE: CVE-2018-10822 CVSS v3: 8.6 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N) Directory traversal vulnerability in the web interface on D-Link routers: aC/ DWR-116 through 1.06, aC/ DIR-140L through 1.02, aC/ DIR-640L through 1.02, aC/ DWR-512 through 2.02, aC/ DWR-712 through 2.02, aC/ DWR-912 through 2.02, aC/ DWR-921 through 2.02, aC/ DWR-111 through 1.01, aC/ and probably others with the same type of firmware allows remote attackers to read arbitrary files via a /.. or // after "GET /uir" in an HTTP request. NOTE: this vulnerability exists because of an incorrect fix for CVE-2017-6190. PoC: aaaaa a $ curl http://routerip/uir//etc/passwd aaaaa The vulnerability can be used retrieve administrative password using the other disclosed vulnerability - CVE-2018-10824 This vulnerability was reported previously by Patryk Bogdan in CVE-2017-6190 but he reported it is fixed in certain release but unfortunately it is still present in even newer releases. The vulnerability is also present in other D-Link routers and can be exploited not only (as the original author stated) by double dot but also absolutely using double slash. 2 Password stored in plaintext in several series of D-Link routers aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa CVE: CVE-2018-10824 An issue was discovered on D-Link routers: aC/ DWR-116 through 1.06, aC/ DIR-140L through 1.02, aC/ DIR-640L through 1.02, aC/ DWR-512 through 2.02, aC/ DWR-712 through 2.02, aC/ DWR-912 through 2.02, aC/ DWR-921 through 2.02, aC/ DWR-111 through 1.01, aC/ and probably others with the same type of firmware. NOTE: I have changed the filename in description to XXX because the vendor leaves some EOL routers unpatched and the attack is too simple. PoC using the directory traversal vulnerability disclosed at the same time - CVE-2018-10822 aaaaa a $ curl http://routerip/uir//tmp/XXX/0 aaaaa This command returns a binary config file which contains admin username and password as well as many other router configuration settings. By using the directory traversal vulnerability it is possible to read the file without authentication. 3 Shell command injection in httpd server of a several series of D-Link routers aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaa CVE: CVE-2018-10823 CVSS v3: 9.1 (AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H) An issue was discovered on D-Link routers: aC/ DWR-116 through 1.06, aC/ DWR-512 through 2.02, aC/ DWR-712 through 2.02, aC/ DWR-912 through 2.02, aC/ DWR-921 through 2.02, aC/ DWR-111 through 1.01, aC/ and probably others with the same type of firmware. An authenticated attacker may execute arbitrary code by injecting the shell command into the chkisg.htm page Sip parameter. This allows for full control over the device internals. PoC: 1. 2. Request the following URL after login: aaaaa a $ curl http://routerip/chkisg.htm%3FSip%3D1.1.1.1%20%7C%20cat%20 %2Fetc%2Fpasswd aaaaa 3. See the passwd file contents in the response. 4 Exploiting all together aaaaaaaaaaaaaaaaaaaaaaaaa CVSS v3: 10 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H) Taking all the three together it is easy to gain full router control including arbitrary code execution. Description with video: [http://sploit.tech/2018/10/12/D-Link.html] 5 Timeline aaaaaaaaaa aC/ 09.05.2018 - vendor notified aC/ 06.06.2018 - asked vendor about the status because of long vendor response aC/ 22.06.2018 - received a reply that a patch will be released for DWR-116 and DWR-111, for the other devices which are EOL an announcement will be released aC/ 09.09.2018 - still no reply from vendor about the patches or announcement, I have warned the vendor that if I will not get a reply in a month I will publish the disclosure aC/ 12.10.2018 - disclosing the vulnerabilities
