Captive Portal atak hatası



  • Selamlar.
    pfsense 2.0.3 kullanıyorum. Captive Portal ve Freeradius 2 kurduktan sonra system logunda şöyle bir hata gördüm.

    lighttpd[28203]: (mod_fastcgi.c.2676) FastCGI-stderr: ALERT - configured request variable name length limit exceeded - dropped variable '2869DC78B9B5DEDFF5478569AEADAA55MIGBBgkrBgEEAYI3WAOgdDByBgorBgEEAYI3WAMBoGQwYgIDAgABAgJmAQIBQAQIgrK7cVbuAB8EEI3e3smSl348y1Xob8teCFoEOFwiIHnplusASLdUYDwZplus7BO7PhepDjpYEP7QAcj3kQzQslashfYBQ0XiEDmBVUnTrHr12TrUZ29b7b1PMy' (attacker '20.20.20.102', file '/usr/local/captiveportal/index.php')

    Ne anlama geliyor acaba? Yardımcı olursanız sevinirim.



  • Birkaç gündür uyarı görmemiştim. Bugün yine aşağıdaki uyarıları gördüm. Ne anlama geldiği hakkında bilginiz var mı acaba?
