Description

A security flaw has been discovered in liftoff-sr CIPster 1802525be27d33e19a9a83c163e331a1d13b1892. The impacted element is the function CipAttribute::GetAttrData/CipAttribute::SetAttrData of the file ciptypes.h of the component Generic Attribute Logic. Performing a manipulation results in memory corruption. It is possible to initiate the attack remotely. The exploit has been released to the public and may be used for attacks. The patch is named e745d9d4a8ca3a13689066983a1269fe1e567674. It is suggested to install a patch to address this issue.

  "executiveSummary": "A memory corruption vulnerability has been identified in the liftoff-sr CIPster repository, specifically within commit 1802525be27d33e19a9a83c163e331a1d13b1892. The flaw resides in the Generic Attribute Logic component, impacting the CipAttribute::GetAttrData and CipAttribute::SetAttrData functions within the ciptypes.h file. Successful exploitation of this vulnerability leads to memory corruption states, which may compromise the integrity and availability of the affected software. The attack vector is remote, allowing unauthorized threat actors to initiate exploitation over a network interface without requiring prior authentication. Public exploits for this flaw have been released, significantly increasing the risk of active exploitation in the wild. Organizations and users deploying the vulnerable version must apply the official security patch identified by commit hash e745d9d4a8ca3a13689066983a1269fe1e567674 to remediate the risk.",
  "technicalDetails": "The vulnerability is classified as a memory corruption flaw stemming from unsafe handling or parsing of attribute data within the Generic Attribute Logic component of CIPster. Specifically, the root cause is located in the CipAttribute::GetAttrData and CipAttribute::SetAttrData functions defined in ciptypes.h. These functions fail to properly validate boundaries, sizes, or types of data being read from or written to internal memory structures during attribute retrieval or modification operations.\nThe attack flow initiates when a remote attacker crafts a malicious payload designed to interact with the Generic Attribute Logic. Because the application exposes interfaces that can be accessed remotely, the attacker transmits the malformed request containing the exploit payload across the network protocol boundary. Upon receipt, the vulnerable CIPster instance processes the input via CipAttribute::GetAttrData or CipAttribute::SetAttrData without adequate sanity checks or input validation.\nDuring execution of these functions, the uncontrolled data manipulation forces an out-of-bounds write or read condition within the heap or stack memory allocated for attribute storage. This memory corruption overwrites adjacent critical data structures, pointers, or control flow metadata depending on the exact nature of the buffer layout. The exploitation does not mandate local access, pre-existing authentication, or elevated user privileges, making it accessible to any network-adjacent or remote entity capable of communicating with the vulnerable service.\nThe post-exploitation impact of this memory corruption includes potential application crashes resulting in denial of service (DoS), or potentially more severe outcomes such as arbitrary code execution if the memory manipulation can be precisely controlled by the attacker via heap spraying or careful layout manipulation. The availability of a public exploit increases the likelihood of automated scanning and targeted exploitation attempts against exposed systems."
