The vulnerability is due to improper validation of user-supplied input within TFTP requests processed by the affected software. An attacker could exploit this vulnerability by using directory traversal techniques in malicious requests sent to the TFTP service on a targeted device. An exploit could allow the attacker to retrieve arbitrary files from the targeted device, resulting in the disclosure of sensitive information. This vulnerability affects Cisco IOS XR Software releases prior to Release 6.5.2 for Cisco Network Convergence System 1000 Series devices when the TFTP service is enabled.","A vulnerability in the TFTP service of Cisco Network Convergence System 1000 Series software could allow an unauthenticated, remote attacker to retrieve arbi...","2019-02-21T20:29:00.29","2023-03-24T17:47:28.19",7.5,"CVSS:3.1\u002FAV:N\u002FAC:L\u002FPR:N\u002FUI:N\u002FS:U\u002FC:H\u002FI:N\u002FA:N",{"CVSSMetricV31":15,"CVSSMetricV30":29,"CVSSMetricV2":36,"CVSSMetricV40":26},[16],{"Source":17,"Type":18,"CVSSData":19,"ExploitabilityScore":27,"ImpactScore":28},"nvd@nist.gov","Primary",{"Version":20,"VectorString":13,"AttackVector":21,"AttackComplexity":22,"PrivilegesRequired":23,"UserInteraction":23,"Scope":24,"ConfidentialityImpact":25,"IntegrityImpact":23,"AvailabilityImpact":23,"BaseScore":12,"BaseSeverity":25,"ExploitCodeMaturity":26,"RemediationLevel":26,"ReportConfidence":26,"TemporalScore":26,"TemporalSeverity":26,"ConfidentialityRequirement":26,"IntegrityRequirement":26,"AvailabilityRequirement":23,"ModifiedAttackVector":26,"ModifiedAttackComplexity":26,"ModifiedPrivilegesRequired":26,"ModifiedUserInteraction":26,"ModifiedScope":26,"ModifiedConfidentialityImpact":26,"ModifiedIntegrityImpact":26,"ModifiedAvailabilityImpact":26,"EnvironmentalScore":26,"EnvironmentalSeverity":26},"3.1","NETWORK","LOW","NONE","UNCHANGED","HIGH",null,3.9,3.6,[30],{"Source":31,"Type":32,"CVSSData":33,"ExploitabilityScore":27,"ImpactScore":28},"ykramarz@cisco.com","Secondary",{"Version":34,"VectorString":35,"AttackVector":21,"AttackComplexity":22,"PrivilegesRequired":23,"UserInteraction":23,"Scope":24,"ConfidentialityImpact":25,"IntegrityImpact":23,"AvailabilityImpact":23,"BaseScore":12,"BaseSeverity":25,"ExploitCodeMaturity":26,"RemediationLevel":26,"ReportConfidence":26,"TemporalScore":26,"TemporalSeverity":26,"ConfidentialityRequirement":26,"IntegrityRequirement":26,"AvailabilityRequirement":26,"ModifiedAttackVector":26,"ModifiedAttackComplexity":26,"ModifiedPrivilegesRequired":26,"ModifiedUserInteraction":26,"ModifiedScope":26,"ModifiedConfidentialityImpact":26,"ModifiedIntegrityImpact":26,"ModifiedAvailabilityImpact":26,"EnvironmentalScore":26,"EnvironmentalSeverity":26},"3.0","CVSS:3.0\u002FAV:N\u002FAC:L\u002FPR:N\u002FUI:N\u002FS:U\u002FC:H\u002FI:N\u002FA:N",[37],{"Source":17,"Type":18,"CVSSData":38,"BaseSeverity":43,"ExploitabilityScore":44,"ImpactScore":45,"ACInsufInfo":26,"ObtainAllPrivilege":26,"ObtainUserPrivilege":26,"ObtainOtherPrivilege":26,"UserInteractionRequired":26},{"Version":39,"VectorString":40,"AccessVector":21,"AccessComplexity":22,"Authentication":23,"ConfidentialityImpact":41,"IntegrityImpact":23,"AvailabilityImpact":23,"BaseScore":42,"BaseSeverity":26,"Exploitability":26,"RemediationLevel":26,"ReportConfidence":26,"TemporalScore":26,"CollateralDamagePotential":26,"TargetDistribution":26,"ConfidentialityRequirement":26,"IntegrityRequirement":26,"AvailabilityRequirement":26,"EnvironmentalScore":26},"2.0","AV:N\u002FAC:L\u002FAu:N\u002FC:P\u002FI:N\u002FA:N","PARTIAL",5,"MEDIUM",10,2.9,0.06282,[46,46,46,46,46,46,46],"High",[50],{"vendor":51,"product":52,"version":53,"criteria":54,"vulnerable":4},"cisco","ios_xr","*","cpe:2.3:o:cisco:ios_xr:*:*:*:*:*:*:*:*",1,[57,64],{"url":58,"source":59,"tags":60},"http:\u002F\u002Fwww.securityfocus.com\u002Fbid\u002F107107","Securityfocus",[61,62,63],"Broken Link","Third Party Advisory","VDB Entry",{"url":65,"source":66,"tags":67},"https:\u002F\u002Ftools.cisco.com\u002Fsecurity\u002Fcenter\u002Fcontent\u002FCiscoSecurityAdvisory\u002Fcisco-sa-20190220-ncs","Cisco",[68],"Vendor Advisory",2,[71,79],{"id":72,"name":73,"description":74,"extendedDescription":75,"status":76,"abstraction":77,"structure":78},"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.

These parties include:\nInformation exposures can occur in different ways:\nIt is common practice to describe any loss of confidentiality as an \"information exposure,\" but this can lead to overuse of CWE-200 in CWE mapping. From the CWE perspective, loss of confidentiality is a technical impact that can arise from dozens of different weaknesses, such as insecure file permissions or out-of-bounds read.  CWE-200 and its lower-level descendants are intended to cover the mistakes that occur in behaviors that explicitly manage, store, transfer, or cleanse sensitive information.","Draft","Class",false,[],{"title":89,"metaDescription":90,"keywords":91,"canonicalUrl":92,"structuredData":93},"What is CVE-2019-1681?
