The issue is due to improper sanitization of user-supplied input in HTTP request parameters that describe filenames and pathnames. An attacker could exploit this vulnerability by using directory traversal techniques to submit a path to a desired file location. A successful exploit could allow the attacker to view system files on the targeted device, which may contain sensitive information.","A vulnerability in the web-based interface of Cisco Wireless LAN Controller Software could allow an authenticated, remote attacker to view sensitive informat...","2018-10-17T22:29:00.457","2023-02-03T19:21:26.437",6.5,"CVSS:3.1\u002FAV:N\u002FAC:L\u002FPR:L\u002FUI:N\u002FS:U\u002FC:H\u002FI:N\u002FA:N",{"CVSSMetricV31":15,"CVSSMetricV30":30,"CVSSMetricV2":37,"CVSSMetricV40":27},[16],{"Source":17,"Type":18,"CVSSData":19,"ExploitabilityScore":28,"ImpactScore":29},"nvd@nist.gov","Primary",{"Version":20,"VectorString":13,"AttackVector":21,"AttackComplexity":22,"PrivilegesRequired":22,"UserInteraction":23,"Scope":24,"ConfidentialityImpact":25,"IntegrityImpact":23,"AvailabilityImpact":23,"BaseScore":12,"BaseSeverity":26,"ExploitCodeMaturity":27,"RemediationLevel":27,"ReportConfidence":27,"TemporalScore":27,"TemporalSeverity":27,"ConfidentialityRequirement":27,"IntegrityRequirement":27,"AvailabilityRequirement":23,"ModifiedAttackVector":27,"ModifiedAttackComplexity":27,"ModifiedPrivilegesRequired":27,"ModifiedUserInteraction":27,"ModifiedScope":27,"ModifiedConfidentialityImpact":27,"ModifiedIntegrityImpact":27,"ModifiedAvailabilityImpact":27,"EnvironmentalScore":27,"EnvironmentalSeverity":27},"3.1","NETWORK","LOW","NONE","UNCHANGED","HIGH","MEDIUM",null,2.8,3.6,[31],{"Source":32,"Type":33,"CVSSData":34,"ExploitabilityScore":28,"ImpactScore":29},"ykramarz@cisco.com","Secondary",{"Version":35,"VectorString":36,"AttackVector":21,"AttackComplexity":22,"PrivilegesRequired":22,"UserInteraction":23,"Scope":24,"ConfidentialityImpact":25,"IntegrityImpact":23,"AvailabilityImpact":23,"BaseScore":12,"BaseSeverity":26,"ExploitCodeMaturity":27,"RemediationLevel":27,"ReportConfidence":27,"TemporalScore":27,"TemporalSeverity":27,"ConfidentialityRequirement":27,"IntegrityRequirement":27,"AvailabilityRequirement":27,"ModifiedAttackVector":27,"ModifiedAttackComplexity":27,"ModifiedPrivilegesRequired":27,"ModifiedUserInteraction":27,"ModifiedScope":27,"ModifiedConfidentialityImpact":27,"ModifiedIntegrityImpact":27,"ModifiedAvailabilityImpact":27,"EnvironmentalScore":27,"EnvironmentalSeverity":27},"3.0","CVSS:3.0\u002FAV:N\u002FAC:L\u002FPR:L\u002FUI:N\u002FS:U\u002FC:H\u002FI:N\u002FA:N",[38],{"Source":17,"Type":18,"CVSSData":39,"BaseSeverity":26,"ExploitabilityScore":45,"ImpactScore":46,"ACInsufInfo":27,"ObtainAllPrivilege":27,"ObtainUserPrivilege":27,"ObtainOtherPrivilege":27,"UserInteractionRequired":27},{"Version":40,"VectorString":41,"AccessVector":21,"AccessComplexity":22,"Authentication":42,"ConfidentialityImpact":43,"IntegrityImpact":23,"AvailabilityImpact":23,"BaseScore":44,"BaseSeverity":27,"Exploitability":27,"RemediationLevel":27,"ReportConfidence":27,"TemporalScore":27,"CollateralDamagePotential":27,"TargetDistribution":27,"ConfidentialityRequirement":27,"IntegrityRequirement":27,"AvailabilityRequirement":27,"EnvironmentalScore":27},"2.0","AV:N\u002FAC:L\u002FAu:S\u002FC:P\u002FI:N\u002FA:N","SINGLE","PARTIAL",4,8,2.9,0.04638,[47,47,47,47,47,47,47],"Medium",[51],{"vendor":52,"product":53,"version":54,"criteria":55,"vulnerable":4},"cisco","wireless_lan_controller_software","8.2\\(151.0\\)","cpe:2.3:o:cisco:wireless_lan_controller_software:8.2\\(151.0\\):*:*:*:*:*:*:*",1,[58,65,69],{"url":59,"source":60,"tags":61},"http:\u002F\u002Fwww.securityfocus.com\u002Fbid\u002F105671","Securityfocus",[62,63,64],"Broken Link","Third Party Advisory","VDB Entry",{"url":66,"source":67,"tags":68},"http:\u002F\u002Fwww.securitytracker.com\u002Fid\u002F1041926","Securitytracker",[62,63,64],{"url":70,"source":71,"tags":72},"https:\u002F\u002Ftools.cisco.com\u002Fsecurity\u002Fcenter\u002Fcontent\u002FCiscoSecurityAdvisory\u002Fcisco-sa-20181017-wlc-traversal","Cisco",[73],"Vendor Advisory",3,[76],{"id":77,"name":78,"description":79,"extendedDescription":80,"status":81,"abstraction":82,"structure":83},"CWE-22","Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')","The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.","Many file operations are intended to take place within a restricted directory. By using special elements such as \"..\" and \"\u002F\" separators, attackers can escape outside of the restricted location to access files or directories that are elsewhere on the system. One of the most common special elements is the \"..\u002F\" sequence, which in most modern operating systems is interpreted as the parent directory of the current location. This is referred to as relative path traversal. Path traversal also covers the use of absolute pathnames such as \"\u002Fusr\u002Flocal\u002Fbin\" to access unexpected files.
