PORT STATE SERVICE VERSION
3299/tcp open saprouter?
```
This is a summary of the post from [https://blog.rapid7.com/2014/01/09/piercing-saprouter-with-metasploit/](https://blog.rapid7.com/2014/01/09/piercing-saprouter-with-metasploit/)
## Kuelewa Uvunjaji wa SAProuter kwa Metasploit
SAProuter inafanya kazi kama proxy ya kinyume kwa mifumo ya SAP, hasa kudhibiti ufikiaji kati ya mtandao wa intaneti na mitandao ya ndani ya SAP. Mara nyingi inakabiliwa na mtandao wa intaneti kwa kuruhusu bandari ya TCP 3299 kupitia moto wa shirika. Mpangilio huu unafanya SAProuter kuwa lengo la kuvutia kwa pentesting kwa sababu inaweza kutumikia kama lango la mitandao ya ndani yenye thamani kubwa.
**Kuchunguza na Kukusanya Taarifa**
Kwanza, uchunguzi unafanywa kubaini ikiwa SAP router inafanya kazi kwenye IP fulani kwa kutumia moduli ya **sap_service_discovery**. Hatua hii ni muhimu kwa kuanzisha uwepo wa SAP router na bandari yake iliyo wazi.
```text
msf> use auxiliary/scanner/sap/sap_service_discovery
msf auxiliary(sap_service_discovery) > set RHOSTS 1.2.3.101
msf auxiliary(sap_service_discovery) > run
```
Following the discovery, further investigation into the SAP router's configuration is carried out with the **sap_router_info_request** module to potentially reveal internal network details.
Baada ya kugundua, uchunguzi zaidi wa usanidi wa SAP router unafanywa kwa kutumia moduli ya **sap_router_info_request** ili uweze kufichua maelezo ya mtandao wa ndani.
```text
msf auxiliary(sap_router_info_request) > use auxiliary/scanner/sap/sap_router_info_request
msf auxiliary(sap_router_info_request) > set RHOSTS 1.2.3.101
msf auxiliary(sap_router_info_request) > run
```
**Kuhesabu Huduma za Ndani**
Kwa ufahamu wa mtandao wa ndani ulio pata, moduli ya **sap_router_portscanner** inatumika kuchunguza mwenyeji wa ndani na huduma kupitia SAProuter, ikiruhusu kuelewa kwa undani mitandao ya ndani na usanidi wa huduma.
```text
msf auxiliary(sap_router_portscanner) > set INSTANCES 00-50
msf auxiliary(sap_router_portscanner) > set PORTS 32NN
```
Moduli huu una uwezo wa kubadilika katika kulenga mifano maalum ya SAP na bandari, na kufanya kuwa chombo chenye ufanisi kwa uchunguzi wa kina wa mtandao wa ndani.
**Uhesabuji wa Juu na Ramani za ACL**
Kuchunguza zaidi kunaweza kufichua jinsi Orodha za Udhibiti wa Ufikiaji (ACLs) zilivyowekwa kwenye SAProuter, zikielezea ni muunganisho gani unaruhusiwa au kuzuia. Taarifa hii ni muhimu katika kuelewa sera za usalama na uwezekano wa udhaifu.
```text
msf auxiliary(sap_router_portscanner) > set MODE TCP
msf auxiliary(sap_router_portscanner) > set PORTS 80,32NN
```
**Blind Enumeration of Internal Hosts**
Katika hali ambapo taarifa za moja kwa moja kutoka kwa SAProuter ni chache, mbinu kama vile blind enumeration zinaweza kutumika. Njia hii inajaribu kukisia na kuthibitisha uwepo wa majina ya ndani ya mwenyeji, ikifunua malengo yanayoweza kuwa bila anwani za IP za moja kwa moja.
**Leveraging Information for Penetration Testing**
Baada ya kuchora ramani ya mtandao na kubaini huduma zinazopatikana, wapimaji wa penetration wanaweza kutumia uwezo wa proxy wa Metasploit kuhamasisha kupitia SAProuter kwa ajili ya uchunguzi zaidi na unyakuzi wa huduma za ndani za SAP.
```text
msf auxiliary(sap_hostctrl_getcomputersystem) > set Proxies sapni:1.2.3.101:3299
msf auxiliary(sap_hostctrl_getcomputersystem) > set RHOSTS 192.168.1.18
msf auxiliary(sap_hostctrl_getcomputersystem) > run
```
**Hitimisho**
Mbinu hii inasisitiza umuhimu wa usanidi salama wa SAProuter na kuonyesha uwezekano wa kufikia mitandao ya ndani kupitia upimaji wa udukuzi ulioelekezwa. Kuweka salama SAP routers ipasavyo na kuelewa jukumu lao katika usanifu wa usalama wa mtandao ni muhimu kwa kulinda dhidi ya ufikiaji usioidhinishwa.
