This typically means that the malformed data becomes a username and no password. If this occurs, clients can circumvent authentication and get access to the broker by using the malformed username. In particular, a blank line will be treated as a valid empty username. Other security measures are unaffected. Users who have only used the mosquitto_passwd utility to create and modify their password files are unaffected by this vulnerability.","When Eclipse Mosquitto version 1.0 to 1.5.5 (inclusive) is configured to use a password file for authentication, any malformed data in the password file will...","2019-03-27T18:29:00.367","2019-10-09T23:34:04.137",8.1,"CVSS:3.0\u002FAV:N\u002FAC:H\u002FPR:N\u002FUI:N\u002FS:U\u002FC:H\u002FI:H\u002FA:H",{"CVSSMetricV31":15,"CVSSMetricV30":16,"CVSSMetricV2":28,"CVSSMetricV40":15},null,[17],{"Source":18,"Type":19,"CVSSData":20,"ExploitabilityScore":26,"ImpactScore":27},"nvd@nist.gov","Primary",{"Version":21,"VectorString":13,"AttackVector":22,"AttackComplexity":23,"PrivilegesRequired":24,"UserInteraction":24,"Scope":25,"ConfidentialityImpact":23,"IntegrityImpact":23,"AvailabilityImpact":23,"BaseScore":12,"BaseSeverity":23,"ExploitCodeMaturity":15,"RemediationLevel":15,"ReportConfidence":15,"TemporalScore":15,"TemporalSeverity":15,"ConfidentialityRequirement":15,"IntegrityRequirement":15,"AvailabilityRequirement":15,"ModifiedAttackVector":15,"ModifiedAttackComplexity":15,"ModifiedPrivilegesRequired":15,"ModifiedUserInteraction":15,"ModifiedScope":15,"ModifiedConfidentialityImpact":15,"ModifiedIntegrityImpact":15,"ModifiedAvailabilityImpact":15,"EnvironmentalScore":15,"EnvironmentalSeverity":15},"3.0","NETWORK","HIGH","NONE","UNCHANGED",2.2,5.9,[29],{"Source":18,"Type":19,"CVSSData":30,"BaseSeverity":33,"ExploitabilityScore":36,"ImpactScore":37,"ACInsufInfo":15,"ObtainAllPrivilege":15,"ObtainUserPrivilege":15,"ObtainOtherPrivilege":15,"UserInteractionRequired":15},{"Version":31,"VectorString":32,"AccessVector":22,"AccessComplexity":33,"Authentication":24,"ConfidentialityImpact":34,"IntegrityImpact":34,"AvailabilityImpact":34,"BaseScore":35,"BaseSeverity":15,"Exploitability":15,"RemediationLevel":15,"ReportConfidence":15,"TemporalScore":15,"CollateralDamagePotential":15,"TargetDistribution":15,"ConfidentialityRequirement":15,"IntegrityRequirement":15,"AvailabilityRequirement":15,"EnvironmentalScore":15},"2.0","AV:N\u002FAC:M\u002FAu:N\u002FC:P\u002FI:P\u002FA:P","MEDIUM","PARTIAL",6.8,8.6,6.4,0.01475,[38,38,38,38,38,38,38],"High",[42],{"vendor":43,"product":44,"version":45,"criteria":46,"vulnerable":4},"eclipse","mosquitto","*","cpe:2.3:a:eclipse:mosquitto:*:*:*:*:*:*:*:*",1,[49,56],{"url":50,"source":51,"tags":52},"https:\u002F\u002Fbugs.eclipse.org\u002Fbugs\u002Fshow_bug.cgi?id=543401","Eclipse",[53,54,55],"Exploit","Issue Tracking","Vendor Advisory",{"url":57,"source":58,"tags":59},"https:\u002F\u002Flists.debian.org\u002Fdebian-lts-announce\u002F2019\u002F10\u002Fmsg00035.html","Debian",[],2,[62,70],{"id":63,"name":64,"description":65,"extendedDescription":66,"status":67,"abstraction":68,"structure":69},"CWE-287","Improper Authentication","When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.","","Draft","Class","Simple",{"id":71,"name":72,"description":73,"extendedDescription":66,"status":74,"abstraction":75,"structure":69},"CWE-703","Improper Check or Handling of Exceptional Conditions","The product does not properly anticipate or handle exceptional conditions that rarely occur during normal operation of the product.","Incomplete","Pillar",false,[],{"title":79,"metaDescription":80,"keywords":81,"canonicalUrl":82,"structuredData":83},"What is CVE-2018-12551?
