This attack requires a user to use a terminal application that translates ANSI escape codes to read the malicious log file locally in the vulnerable terminal. The vulnerability also requires additional user interaction to succeed. \n\nThe vulnerability does not directly affect Splunk ITSI. The indirect impact on Splunk ITSI can vary significantly depending on the permissions in the vulnerable terminal application, as well as where and how the user reads the malicious log file. For example, users can copy the malicious file from Splunk ITSI and read it on their local machine.","In Splunk IT Service Intelligence (ITSI) versions below below 4.13.3, 4.15.3, or 4.17.1, a malicious actor can inject American National Standards Institute (...","2023-08-30T17:15:11.08","2024-12-10T18:15:26.88",8.6,"CVSS:3.1\u002FAV:L\u002FAC:L\u002FPR:N\u002FUI:R\u002FS:C\u002FC:H\u002FI:H\u002FA:H",{"CVSSMetricV31":15,"CVSSMetricV30":27,"CVSSMetricV2":27,"CVSSMetricV40":27},[16,30],{"Source":17,"Type":18,"CVSSData":19,"ExploitabilityScore":28,"ImpactScore":29},"prodsec@splunk.com","Secondary",{"Version":20,"VectorString":13,"AttackVector":21,"AttackComplexity":22,"PrivilegesRequired":23,"UserInteraction":24,"Scope":25,"ConfidentialityImpact":26,"IntegrityImpact":26,"AvailabilityImpact":26,"BaseScore":12,"BaseSeverity":26,"ExploitCodeMaturity":27,"RemediationLevel":27,"ReportConfidence":27,"TemporalScore":27,"TemporalSeverity":27,"ConfidentialityRequirement":27,"IntegrityRequirement":27,"AvailabilityRequirement":26,"ModifiedAttackVector":27,"ModifiedAttackComplexity":27,"ModifiedPrivilegesRequired":27,"ModifiedUserInteraction":27,"ModifiedScope":27,"ModifiedConfidentialityImpact":27,"ModifiedIntegrityImpact":27,"ModifiedAvailabilityImpact":27,"EnvironmentalScore":27,"EnvironmentalSeverity":27},"3.1","LOCAL","LOW","NONE","REQUIRED","CHANGED","HIGH",null,1.8,6,{"Source":31,"Type":32,"CVSSData":33,"ExploitabilityScore":28,"ImpactScore":29},"nvd@nist.gov","Primary",{"Version":20,"VectorString":13,"AttackVector":21,"AttackComplexity":22,"PrivilegesRequired":23,"UserInteraction":24,"Scope":25,"ConfidentialityImpact":26,"IntegrityImpact":26,"AvailabilityImpact":26,"BaseScore":12,"BaseSeverity":26,"ExploitCodeMaturity":27,"RemediationLevel":27,"ReportConfidence":27,"TemporalScore":27,"TemporalSeverity":27,"ConfidentialityRequirement":27,"IntegrityRequirement":27,"AvailabilityRequirement":26,"ModifiedAttackVector":27,"ModifiedAttackComplexity":27,"ModifiedPrivilegesRequired":27,"ModifiedUserInteraction":27,"ModifiedScope":27,"ModifiedConfidentialityImpact":27,"ModifiedIntegrityImpact":27,"ModifiedAvailabilityImpact":27,"EnvironmentalScore":27,"EnvironmentalSeverity":27},0.00253,[34,34,34,34,34,34,34],"High",[38,43],{"vendor":39,"product":40,"version":41,"criteria":42,"vulnerable":4},"splunk","it_service_intelligence","*","cpe:2.3:a:splunk:it_service_intelligence:*:*:*:*:*:*:*:*",{"vendor":39,"product":40,"version":44,"criteria":45,"vulnerable":4},"4.17.0","cpe:2.3:a:splunk:it_service_intelligence:4.17.0:*:*:*:*:*:*:*",2,[48,53],{"url":49,"source":50,"tags":51},"https:\u002F\u002Fadvisory.splunk.com\u002Fadvisories\u002FSVD-2023-0810","Splunk",[52],"Vendor Advisory",{"url":49,"source":50,"tags":54},[52],[56,64],{"id":57,"name":58,"description":59,"extendedDescription":60,"status":61,"abstraction":62,"structure":63},"CWE-116","Improper Encoding or Escaping of Output","The product prepares a structured message for communication with another component, but encoding or escaping of the data is either missing or done incorrectly.
